Just got a k5, need wiring help

Heres the backgroud, I work at a dollarauto.com I buy cars from auctions and resell them. But i recently bought a 82 k5 with a new 350 in it and new tranny for 500 dollars. 6" pro comp lift, Edelbrock headers,heads,carb,manfold, comp cam, etc. All that good stuff. Now here is the problem whoever owned it before i bought it did all the wiring themselfs. Not good either. One long wire to the fuel pump has 3 different colored wires just twist tied on. I need a pic of diagram of the engine bay so i can redo the wiring. My problem i am running into now is i can get it started but it turns off after 10 seconds or so. The wiring to the starter is worse than the fuel pump. I know this car runs because i test drove it but day of the auction someone messed with it. Unhooked all the wiring, stole the valve covers, air filter, grille [img]images/graemlins/frown.gif[/img] Anyway if anyone could please help me

I don't have a diagram for you, but if you're planning on keeping it, I'd consider getting a new harness for it. Check out painlessperformance.com
I haven't used their products myself, but know someone who has, and only has good things to say about it.

Yeah thats what i was looking into. I just want this truck for a work truck as of right now. But the tranny is either going out or no fluid because of a leak. I am going to look at it tomarrow. I have a 72 chevelle coming to me later this week that i am restoring. I just wanted another car to have fun in while i restore this car

Get a subscrition to Alldata the wiring diagrams are online as well as lots of other things. I buy them for all my vehicles. Better than chilton, a little less detailed than a full shop manual.

If it is an '82 and it has an electric fuel pump, the stock wiring diagrams aren't going to help you a whole lot.

Re: Just got a k5, need wiring help

It didn't come with an electric fuel pump in 1982. It needs to have a relay to run one. Someone stupid might run the electric fuel pump off the choke wire.

There is only one wire that goes to the starter from the ignition switch and it goes to the solenoid. The rest go to the battery, alternator, and main power take off to the fuse block.

The wiring is dirt simple on these trucks so either redo it yourself or go get a harness out of the junkyard. I recommend obtaining both a Haynes and Chilton manual to ease the repair. The diagram is several pages long because it includes the ESC junk which you probably don't have anymore.

Re: Just got a k5, need wiring help

I just want to see what a normal one would be like, I know its simple but this guy was a moron. He has so many wires that are just dead ends or not connected, and like i said there is one wire that is made up of 3 different wires. So i am looking just for a pic or something to help me along. I am use to working on a 94 s-10. My other question is what tranny should i put in? I think mine is pretty well shot and i work at a tow truck company so i can pull any tranny out of any car i want [img]images/graemlins/smile.gif[/img]
