LS1 Engine Wiring harness
I have a very nice LS1 engine harness. Just bought it from a guy on LS1tech, but changing plans. $150 + shipping

98 F-body, T56, but it looks like the harness is actually pinned for both from GM.

Re: LS1 Engine Wiring harness
t56 and auto harnesses are unique. Also, the 98 harness is unique compared to the 99-02, which is why I was asking.

Re: LS1 Engine Wiring harness
I know the 98 is different, let me double check the plugs etc for the tranny. I'll post back 100%

Just verified the pinouts. It's for a T56, no pins for TCC control, just reverse lockout.
