You are not going to find a "how to" guide how to do this. You are going to have to look at the FSM for both vehicles and piece stuff together on your own.

I won't be much help, i'm in the same boat, well maybe not quite as my engine runs, but the wiring is a big ol bag of snakes. Here is the Factory Service Manual, i'm sure it has wiring diagrams.

Also, chiltons and Haynes books would have wiring diagrams...

 

it might also help if you let us know whether or not the guy replaced the wiring harness with the 22r or hacked at the 20r. But with something like this as the wabbit says, you are most likely gonna be on your own with this one.

putting up photos of questionable stuff might help as well.

 

Welcome to the forum!

 

thanks guys for the replies. seems like a nice place to chat about trucks. the guy didn't change the wring harness as for as i can tell. the wires over by the battery r all cut up but nothing on the alternater side is mess up. i can get the truck 2 run but i don't know if it is right and of course it's not charging. i will try and get some pics today and try and post them. thaks again guys

 

How do i post a picture that i have saved on the computer? The only thing i see is how to add a link to a picture online!

 

advanced reply scroll down to under where you type and you will see a manage attachments button.

 

ok thanks just tried that and the pic is to big but i cant figure out how to make it smaller

 

Do a search, someone here swapped a late model alternator into a truck a few months ago, they removed the voltage regulator and it was a matter of connecting the wires from the voltage regulator to the plug on the new alternator.

 

thanks man i have been doing some research today and lc engineering has a mounting kit 2 put a gm alternater one wire and replace all of that other stuff thanks again for your help.
