The first thing to find out is what throttle body is on the manifold. Does it match the connectors on the harness? The early DBW's are different than the later ones. Also, the early DBW's used a TAC module (throttle actuator control), do you have that for the harness? I think that a harness for an 02 LM7 would be the early version, but the throttle body on an 05 LM7 would be the later version. Don't quote me on that, I don't know which year they changed.

The 2002 wiring harness will be pinned for a red/blue P01 style PCM. 2005 would've used a green/blue P59. Which PCM do you have currently and what color are the retainers on the PCM connectors of your harness?
