if you can afford a harness then thats the way to go. if you cant, get a wiring diagram of the motor, and hook up what needs to be hooked up to make it run. i used the stock harness on my truck, but not sure i'd do it again. i had to get a new computer chip to by-pass the anti- theft, but you don't have a chip, so i guess somebody would have to change it in your computer.

i was also planing on using all the harnesses becuase i used the caprice steering colum and brakes and all the wiring for the lights and let me tell you theres alot of wires.. im not of a complete made to order kit for the entire wiring system on the truck

if you have worked with wiring before go for it , if not good luck. you still need a diagram so you can identify what everything is. be sure to hook up all of the grounds.

thanks for the help... does anybody knw if i can lose my egr and cats or will it just be more problems than its worth.. its bone stock right now and id like to get the truck running and driving before i tear it down and build the snot out of it..

the cats you can ditch .but the engine was designed to have the egr operational for best efficiency (camshaft)if you block off the egr without shutting that flag off in the pcm you will set a trouble code that (might) leave you in limp home mode or stuck in open loop (rich- warm up ) all the time..my sug. is to leave the egr valve on /plugged ..remove the vaccum lines ect. and the egr sensor plugged in ..as far as the V.A.T.S. vehicle anti theft system goes you can overide it for 2 bucks at radio shack..
thats if you don't have the original key..

hey thanks for the info.. i dont have a chip in my key but idont know if that makes a difference?
