I use the instructions Peter Smith came out with about 7 years ago.

Here is the wiring harness we make. The pins are already on the wires. The connector is available from Porsche or BMW, but I do not know what you were trying to use.

Now that's a beautiful looking harness Tool Pants. How much do you guys sell them for?

I don't sell them because it is so simple to make yourself. Peter Smith is a shop foreman, PCA tech advisor, and he figured out how to make it look like factory, and just plug it in. He gave me a harness years ago and I took it apart, duplicated it, and improved it a bit. With a 2001 up you do not even need to splice the VW wires.

At our work on cars I usually make the harness. Last time I was so busy I got the owner started, then told him to finish by looking at a diagram I had made. He made it and it worked. He forgot to bring the connector so my spare blue BMW connector is in the picture.

Tool Pants,
Would you mind sharing all parts required to fabricate our own wire harness?

Tool Pants · 10-12-2007, 08:13 PM

Need the connector I mentioned. If you buy it from BMW the BMW part number is 61 13 6 909 058.

On your year you need 5 VW wires 000 979 009.

Need 1 ring terminal for the ground wire, 1/4" stud size for 22-18 gauge wire.

Excellent…. Thanks!

Do any of the numbers change for an 02 S?

Same part numbers for 2001-2004 Boxster. Same part number for 2002-2004 996.

If someone reads the renntech link, you need to keep in mind I was talking about a 996, not a Boxster.

The Boxster instrument cluster design changed in 2001, but with the 996 the change was 2002.

I want to do this hack soon but with switches instead of the stalk, but i want to be able to reset or set the settings that the OBC stalk allows you todo... I guess i'd have to buy 1 extra button switch to add that function but my question is, What spot in the connecter would the pin for reset/set be?

Edit: i read in the directions link posted that "Optional: If you want, you can also wire up the Mode Down, Slot 23 (2001-) or Slot 20 (1997-2000) and Speed Gong, Slot 21 (2001-) or Slot 22 (1997-2000). This would require an extra switch."

So i have 1 question, what is the "Mode Down" function?

EDIT: Sorry, i know what Mode Down is now. Its the same as Scroll Down.... not sure that and speed gong is that important.
