ThirdGen (F-Body) Swap help
I thought that you had to splice the two together for it to work. I'm not going carbed, I'm doing the EFI, and you have to combine the two engine harnesses so that the LS1 will operate the speedo and stuff in the car.

now just find the connector pinouts for the LS1 harness you have... if you have a 99-02 fbody harness, it'll be easy to find.
