So here's where my swap is at have the 5.3 in and street and sand performance harness and ECM all hooked up. Problem is I had a Craigslist hack try and finish up project and he cut up 96 harness. This is a wiring nightmare. Does anyone know of affordable options to control ECM and trans and fuel. I see Holley makes some stuff but it's almost a thousand bucks. I'm ready to set fire to this truck.
