Wiring harnesses Being that LSx engines seem to be so similar, I am wondering something. Would I be able to use an LS6 engine wiring harness with an LM7 ECM to run an LM7 engine?
Basically, i have an '03 CTS... I also have an LM7/4L80E laying around. the '04 cadillac CTS-V came with an LS6. so, i am wondering if I could use the CTS-V engine harness with the LM7 computer. Or if I would even need to do that. I have the engine harness and ECM that came with the LM7 but I figured the CTS-V harness might be better since it is a factory Cadillac option. I was hoping to be able to swap in the CTS-V gauge cluster with it and thought the CTS-V engine harness might help in some way...?
