Topic: 20r to 22r need help

[yotadork83]

i recently picked up a 79 pickup long bed for free that was in exellent condition but had a blown head gasget it already had been changed two a 22r but someone stole a bunch of the componets like the coil and the alternater.   i swaped my motor and tranny in from a 83 and cant figure out how to wire up every thing. i need help bad cause know im stuck with two trucks that dont run.

i got a 84 with a 22r i think i have the onwers manual and it might have a wireing guide in it or just pickup a 83 shop manual. at kragens and use a diagram from there ill look in my ownersmanual tonight and see if theres one. id like to just be able to help u from my brain but unless im looking at my truck i cant remember anything. if u got any specific questions i could look at my trucks wireing and help u out

My motor is out right now, but I'll go down and take some pictures of the alternator wires and coil wires after work. Any other wirings that you need? I'll also try to scan the Haynes wiring diagrams tonight so that you have have those as well.

I wouldn't think there would be much difference between the 20r and the 22r, just the head design and smaller bore.

just not sure if i need a 20r coil and alternator it might be the easiest way out just don't have eather of them and don't know if it will work. any one have a extra of eather that is willing to trade

the 20R  alt will bolt right in, but you gotta have the external regulator,  if you have that on the 79  just get the 20R  alt

but the 22R alt  usually has a better output,  and internal regulator


where are you located
