what wiring harness (aftermarket)is the easiest and best quailty for a guys buck?OR is it better to just have my factory one redone?
the engine is a 6.0l with a 4l80e behind it.
Any idea how much horse power it would have?It is out of an 2001 gmc 2500hd 4x4 if it makes any differance
Check out www.nelsonperformance.com where they make a nice clean harness for conversions. Their price is nice, too. You will have whatever HP your engine was designed to output from the factory and a little more if you also get nelsonperformance to performance tune you a PCM.
