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.

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.

Yes, you can add the extra switch to be able to scroll up and down instead of just one way through the OBC, and speed gonging allows you to set a speed. Then when you reach that speed the car beeps. Neither of those seem like features worth spending an extra $50 dollars to get.

Bigb just did the retrofit with a single switch on his 2001.

We have done 100 of the OBC retrofits over the years. With the stalk or switch. No one has asked me to do it with 2 switches, but it can be done. Kind of silly if you ask me. You will get all the OBC functions with a single switch, but you cannot set the speed gong.

I find the gong can help keep me in check
