Gentleman. I am looking for an early and a late 996 Cup wiring diagram set. Trying to compare differences between the harnesses.
Let me know please what you got? Thank You!

I have all of the 2003 and 2004 MJ, would have to scan them, which one are you after, what differences do you want to figure out?

I am as specially interested in the connectors behind the driver seat. Want to see if the early harness and the late harness are the same/close/modifiable? These are the plugs connecting the front and rear halves together. But would be super happy to have the whole set of drawings...
Thank You!

I'll take the paper to work tomorrow and scan them to pdf

We are talking about X2/3 and X2/4 (big black and smaller white connector) in sheet 5
As far as I can see the differences are pin 8 in X2/3 (shiftlight) and pin 30 and 3 (speedlimiter, engine relay) in X2/4

But you will see yourself

Yes! Thank You!

There is some work you will need to do for this.

On the early harness the fuel pump relays are on the tunnel of the car, while the late, they are on the front harness. We tried to use an early harness on a late car, chasing down the wiring and trying to make it work with flow through the relays in the early harness, but were never successful. We ended up getting our hands on the late rear body harness that we needed.

We have the early rear body harness, btw, if you have an early (2002 - 2003) car

Thanks
