glad to hear that lance im sure ill be calling you hahaha with many questions so prepare yourself :LOL:
Feel free, you got my number now.
Lance helped me when I had questions too. He understands this ****!? lol:) No...seriously, what I did, was get the GM Service Manuals(theres two) from E-bay. It has everything you need to know regarding the wiring(and everything else) on your year truck. They come in VERY handy with anything you work on.
I am about to put a 5.3 out of an 03 in a 98 that had a 4.3, can I run the truck totally off the new ecu and just re pin certain things? This is hellfires truck also.....
Yep, run it completely off the newer PCM.
www.Helminc.com is where I always bought mine.
