Need LS2 help

I need the pinout for my 05 GTO LS2 going into my 05LJ. Here is the problem; the throttle pedal (original) does not match the Alldata or factory service manual pinout. I appreciate any help, thanks.

I'm finishing up the same swap (05LS2 to 05LJ). Can you post a pic of the pedal?

You're right, the connector view according to Alldata does not appear to match the actual connector. I've encountered this scenario multiple times on different vehicles with Alldata. But the electrical diagram appears to match what you have. It appears to be an 8-position connector with pins 4 and 8 not being used. That would mean 6 wires being used which is consistent with all other APPs of the era. Now you just have to figure out which pin is which number.

GTO stuff in GM is all messed up with lots of errors. AllData of course gets their info from GM. Only reason we can do them, is because we've figured out the screw ups and know where to look. There are good diagrams of the stuff, you just gotta figure out which of the two (or more) is right.


But as for the pedal connector, I'd highly recommend buying one of the J1 harness kits...

Thanks Wayne, you did my tune about 2 weeks ago. It is running fine, and I appreciate the good work and quick turn around. I got the throttle pedal, ALDL, and the C1 all from the donor GTO. I was able to figure it out and everything seems fine at this point (idling and free reving in the garage).
