OBC Hack

[KevinH90]

According to this article on Pelican the change is in the Pin numbers, but not the wires.

You can click on a link in the project write up to access an order page for the parts. It appears to lump all the 97-04 cars together as far as the parts list is concerned.

Good luck with your project.

Does anyone have the layout of the white guage plug for a 99 Boxster?  eyesite isn't what it was and I cannot see the numbers on the plug to know where to put the wires for the 4 stalk wire harness.

You need five wires. Three of one kind and two of another. The yellow VW wires terminate in a special male connector.

You should have three VW wires exactly the same (part # 000-979-009). You cut two of these in half (you now have 4 wires) and install them into the plug-in connector (part # 999-650-056-40) in slots 2,3,4 &5. The cut ends of these wires will be spliced into other wires later. You take the thitrd wire (uncut) and place one end into connector slot #1. You cut the free end of this wire close to the end and crimp on a 6mm eyelet to the end. This eyelet gets connected to ground.

You should also have two other VW wires (part # 000-979-010). You cut these in half. You now have 4 wires. Connect the cut end of these wires to the wires above that occupy slots 2,3,,4 & 5 of the plug-in connector. Label these. The plug-in connectors snaps into the 4th stalk on the steering wheel column. The ground gets place behind a ground screw.

In 2001 and up Boxsters the wires connect to the Grey Instrument Cluster connector in the following order.

#2 to pin #23 on grey cluster
#3 to pin #22 on grey cluster
#4 to pin # 21 on grey cluster
#5 to pin #24 on grey cluster

Hope this helps!

VERY helpful, thank you!  It's not clear what connector to use from most posts.

I have a 2000 996 C2. My computer is already active and i see the temp. I want to add the computer control stalk. I found a three stalk unit here on eBay 

 

Since my car has cruise control I wanted to know if I can just remove the computer stalk from the eBay unit and add it to my existing three stalk unit?

Yes, you can. The OBC stalk is the only one you can remove. It is held on with two Allen screws, and will screw straight on to yours.

Great news! Thanks Richard. Do I need to remove the steering wheel in order to remove add the computer stalk or can it be done while installed?

You can fit it without removing the steering wheel. Turn the wheel 90° each way to get to the screws behind the wheel on the column cover.  The others are easy to get at.

 

Drop me a PM with your email address. I have a DIY I can send you.
