# VW connector pins: single pins, repair wires and part numbers

> Which single pin fits which VW repair wire: MQS, MCON, Micro Timer, JPT, SPT and MCP contacts with part numbers, plus seals, crimping tools and depinning.

- Web page: https://catalog.polo.blue/guides/connector-pins/

Adding a switch, a sensor or a light to a VW, or repairing a broken wire at a plug, comes down to one small part: the contact crimped onto the wire. VW sells it mostly as a repair wire, while the single pin is often cheaper, sometimes unavailable, and never shown next to the wire in the parts catalogue. This guide matches the two up for the common contact families and explains what you need to know to crimp, fit and remove them.

## Basics

### Single pin or repair wire

![Single pin and repair wire of a Junior Power Timer contact](https://catalog.polo.blue/guides/connector-pins/2cdf3da5832ae57a.webp)

*Single pin and repair wire of a Junior Power Timer contact*

VW calls a **repair wire** (Reparaturleitung) a single yellow wire, about 60 cm long, with the same contact crimped on at both ends. Cut it in half and you have two contacts with a tail of wire, ready to be soldered or crimped to the car's wire.

The parts catalogue shows, for a plug or socket housing, which repair wires fit it. It does not show which **single pin** (the bare contact, to be crimped onto your own wire) is the same contact. The tables in [Contact overview](#contacts) close that gap.

Not every repair wire has a single pin to go with it. Over the years VW has dropped many single pins and left only the repair wire (see [Superseded part numbers](#superseded)), probably so that workshops don't need a crimping tool for every contact type. VW does not make the contacts itself, though, and buys them in, so they can be had from other sources.

Most of VW's contacts come from [TE Connectivity](https://www.te.com/), formerly Tyco Electronics, which took over AMP: that is why the name AMP often turns up on VW contacts. Each table below is headed by the name of the contact family, which is the name to look for in TE's catalogues. Two other large makers of automotive connectors are Delphi (now Aptiv) and Lear.

BMW uses a few TE contacts and Mercedes-Benz a good many more, but both charge more than VW. Their numbers are therefore given only where VW has no single pin of its own.

### Male and female contacts

![Male contacts](https://catalog.polo.blue/guides/connector-pins/c60de1da5b086d60.webp)

*Male contacts*

![Female contacts](https://catalog.polo.blue/guides/connector-pins/0fab3b5cd54cf27a.webp)

*Female contacts*

A **female** contact is the one that closes around its counterpart; the **male** contact is the blade or pin that goes into it. Female contacts sit in a **socket** housing, male contacts in a **plug** housing, although in everyday speech every connector is called a plug.

Most contacts you need for a retrofit are female: the car's control units and switches usually carry the male pins.

### Contact width and wire cross-section

![Contact width, here 0.63 mm (MQS)](https://catalog.polo.blue/guides/connector-pins/3b9856614f211f9b.webp)

*Contact width, here 0.63 mm (MQS)*

![Two contacts of one family, for 4.0 mm² and 0.5 mm²](https://catalog.polo.blue/guides/connector-pins/2dde659141aab629.webp)

*Two contacts of one family, for 4.0 mm² and 0.5 mm²*

The more current a connection carries, the larger its contacts. Contact families differ in two ways: the cross-section of the wire they take, and the **contact width**, the width of the blade of the male contact where it touches the female one. It is measured on the male contact, but the female contact of the family carries the same figure, and TE's catalogues and the VW parts catalogue name the family by it.

Two contacts of the same family made for different wire sizes have the same contact end and differ only in the crimp area, so both fit the same housing. That is why the parts catalogue offers every repair wire of a family for a given housing.

### Contact plating

![Contacts with gold-plated contact areas](https://catalog.polo.blue/guides/connector-pins/1784ed2180825051.webp)

*Contacts with gold-plated contact areas*

Contacts are tin-plated as standard; TE also makes them gold-plated and some silver-plated. Gold-plated contacts are meant for places exposed to the weather, such as the engine bay, where they keep the contact from corroding.

VW sells hardly any of them as single pins, so the tables leave them out. Repair wires, however, come gold-plated too: replace the index **E** at the end of the part number with **EA** (000 979 009 E → 000 979 009 EA). Only the contact area is gold-plated, not the whole pin.

### Crimping tools

![Crimping pliers for open-barrel contacts](https://catalog.polo.blue/guides/connector-pins/334b29d8666778b0.webp)

*Crimping pliers for open-barrel contacts*

Working with single pins starts with a proper pair of crimping pliers. Pliers for wire-end ferrules or insulated cable lugs will not do: you need pliers for **non-insulated (open-barrel) contacts**, and they are not cheap. A frame costs roughly 70 to 300 euros and each set of dies 70 to 400, depending on the maker; second-hand ones turn up now and then. A simple pair is enough for large contacts from 1.5 to 2.5 mm², but small cross-sections need precise dies, and a bad crimp shows up later as an intermittent fault deep inside a wiring harness.

Makers name these pliers differently. The easiest way to find the right ones is to search for the contact system you want to crimp:

| Abbreviation | System |
| --- | --- |
| JPT | Junior Power Timer |
| JT | Junior Timer |
| SPT | Standard Power Timer |
| – | Micro Timer |
| MQS | Micro Quadlok System |
| MCP | Multiple Contact Point |

![The parts of a contact](https://catalog.polo.blue/guides/connector-pins/c112c493775436d3.webp)

- **1** Locking lance (primary lock)
- **2** Wire crimp
- **3** Insulation crimp

The die nests differ from one contact type to another. The **wire crimp** should take the shape of a B lying on its side, hence the names B crimp or F crimp. The **insulation crimp** is a B crimp or an O crimp, depending on the contact and its use; on contacts made for a single wire seal it is always an O crimp, as it has to close around the seal.

*A spoiled crimp: an MQS contact in pliers made for larger contacts*

The contact must fill the die nest completely, and the two halves of the die should close parallel. What the photos taught the original authors:

- The simple red Knipex pliers (97 21 215 B) have no ratchet that holds them closed step by step, need a lot of force on larger wires, and their jaws do not close parallel. They are not suitable for MQS contacts.
- The black and red Würth Zebra pliers (0714 107 107, built under licence from the Knipex PreciForce, also sold as Rennsteig PEW 9) also close at an angle, and the contact does not sit well in them: the rests for the wire crimp and the insulation crimp are almost level, so the contact slides forwards or backwards while crimping.
- Pliers with interchangeable dies (the blue ones) are the most versatile. They are sold by Knipex (system pliers), Rennsteig (PEW 12) and TE (Ergocrimp), and work very well even though their jaws do not close perfectly parallel either.
- Only pliers like the yellow ones close fully parallel (Rennsteig PEW 6, Knipex). They crimp beautifully but cover only a narrow range of wire sizes.

### Locking, depinning and pinning

A contact has to stay in its housing despite vibration, so it is held twice. The **primary lock** is the contact's own locking lance (the spring tab shown under [Crimping tools](#tools)), which catches in the housing; it works on each contact separately. The **secondary lock** is part of the housing and holds several contacts at once, usually all of them; housings that combine different contact families sometimes have more than one.

![Three kinds of secondary lock: a flap, an inner part pushed home, a slide](https://catalog.polo.blue/guides/connector-pins/98d50876e5bd16fd.webp)

*A slide lock open (top) and closed (bottom), in a housing sawn open*

Secondary locks come in many forms. On the socket on the left a flap closes over the contacts. In the red socket in the middle the inner part is pushed fully into the outer one, and a web then blocks the long groove of the inner part. The most common kind is the one on the right: a slide on the side of the housing, often purple, which is moved sideways to lock or unlock, or pulled out completely.

To remove a contact, first open the secondary lock, then release the primary lock. In the red socket with an inner part that only takes a small screwdriver to press the lances down. Other housings need a **release tool** (depinning tool) pushed in from the front alongside the contact.

As the lances of the different families differ in width and shape, so do the release tools; whole sets are sold online, but they are seldom worth it. A home-made tool from a heavy-duty staple does the job, as long as it is wide enough and thick enough. Pins with a pointed tip slip past the lance, and a bent paper clip is usually too narrow for the curved lances of many contacts. With the right tool a contact comes out with almost no force: if it does not move when you pull the wire gently, it is not released yet.

### Seals

![Single wire seals and blanking plugs](https://catalog.polo.blue/guides/connector-pins/a6112f68914bc547.webp)

*Single wire seals and blanking plugs*

![A contact made for a seal (top) and a standard one (bottom)](https://catalog.polo.blue/guides/connector-pins/b1b9b75e4d8da7ef.webp)

*A contact made for a seal (top) and a standard one (bottom)*

Connections outside the cabin, in the engine bay, behind the bumpers or in the wheel arches, are exposed to water. Besides gold-plated contacts they use sealed housings: a seal between plug and socket, and a **single wire seal** (SWS) on every wire where it enters the housing. The seal is crimped onto the contact together with the wire, so a contact made for it has a differently shaped insulation crimp.

Seals come in sizes for each contact family and wire cross-section, and unused cavities of a sealed housing are closed with **blanking plugs**; see [Seals and blanking plugs](#seals-overview). The catalogues contradict each other in places on the diameter, length and colour of the seals, so treat that table with some care.

VW sells very few single contacts made for seals, and only some of them as repair wires. Rather than leave the seal out, take a standard contact, slide the seal onto the wire and sit it right behind the contact; with some effort it can even go over the insulation crimp.

![A sealed housing](https://catalog.polo.blue/guides/connector-pins/c605a4bdfce21c70.webp)

*A sealed housing*

Contacts made for seals strictly need their own dies, which are hard to find and expensive. It is easier with pliers that crimp the wire crimp on its own: then close the insulation crimp around the seal with small flat-nosed pliers.

![A sealed housing sawn open: the seal, the primary and the secondary lock](https://catalog.polo.blue/guides/connector-pins/b76cfe5efd4f28f2.webp)

*A sealed housing sawn open: the seal, the primary and the secondary lock*

The parts catalogue seldom says whether a housing is made for seals. Look at its back: a sealed housing has a round opening for each wire.

## Contact overview

Each table lists one contact family by its contact width. A row starts with the wire cross-section of the repair wires; next to each repair wire is the single pin that is the same contact. The cross-section given for a single pin is the largest it is made for: smaller wires crimp too, and within limits a slightly larger one.

Where VW has no single pin, the table gives the number of another maker (BMW, Mercedes-Benz, or the contact's maker). A VW dealer orders single pins in bags of 25; some dealers will sell fewer.

MCON is sometimes wrongly called MCP 1.2. It comes in two versions, Locking Lance (LL) and Clean Body (CB); the numbers and photos here are of the LL version.

The BMW contacts marked MLK belong to Kostal's MLK 1.2 family (Mini Lamellen Kontakt), which is almost identical to MCON: they fit TE's MCON housings.

## Superseded part numbers

Part numbers found online are often no longer valid. The table lists numbers of single pins, seals and repair wires that VW has withdrawn, with what replaced them.

At some point every repair wire got the index E: 000 979 009 became 000 979 009 E, and 000 979 019 A became 000 979 019 EA.

## Where to buy

Single pins are cheaper at VW than repair wires, but these are cent parts that cost far less elsewhere:

- [TME](https://www.tme.eu/en/): contacts and connector housings by the maker's part number (TE and others).
- [DeyTrade Connecting](https://www.automotive-connectors.com/): housings, contacts and seals for German cars.
- [TGS](https://www.t-g-s.de/): contacts, connectors and release tools.
- [Mouser Electronics](https://www.mouser.com/c/connectors/automotive-connectors/): the widest choice of TE contacts. Look up the contact's TE part number in TE's catalogue and search for it; mind the shipping costs.
- [Conrad](https://www.conrad.com/).

The part numbers were compiled between 2011 and 2019: VW keeps withdrawing single pins, so check a number at the dealer before ordering. If you find a mistake, let me know.
