Im swaping a 5.3 LS into my 97 Z28, and the cheapest engine harness ive found is about $750. Its the t56 trans and the engine is driveby wire. I dont even know if that specific harness will plug into my body harness. Any suggestions on website or other companies that might make a cheaper harness? This is a budget build, but im trying to do everything i can right. i went through current performance wiring.
