silveradoriderss Posted January 16, 2014 Report Share Posted January 16, 2014 Hey I have a 2003 Chevy Silverado 50,000 km on the truck and engine caught fire when previously owner had it. I bought it and repaired everything but wondering now the engine harness is all I need remaining the truck has a 5.3 litre engine 4x4 floor shift 3:73 I'm wondering now is there a specific engine Harness I need since I was told I need one from a truck with a M30 tranny RPO code. The part number from the exact harness is 15192312 I am wondering what harnesses would work. If any 2003-2007 classic 5.3 harness will be universal 4x4 would work. Either push button 4x4 or floor shift. Since I cannot find a harness with NO hacks or cuts in it. Thanks pm me or contact me thanks Quote Link to comment Share on other sites More sharing options...
