a hybrid project..almost complete!
super clean 82 cab and bobbed bed..
on my slightly mod'd 79 1st gen chassis, with a de-smogged 20R in it.

interior is wired right: headlights, dash lights, signals, dome light, windshield wipers work good..everythings operational.

motor turns over but wont start/fire..not sure about wiring to alternator/distributor/ coil etc..

most plugs are different out of the 82 harness to '79 20R motor..specificly from coil and igniter. anyone have any ideas on hard wiring? to see if i can get spark??

 

i just put an '81 cab on my '79, and ran into the same wiring problems. basicly i used everything from a post '81 to solve the problems, coil, distributor, and alternator. the only things i had to hard wire the headlights and the soleniod on the carb

 

hmm interesting..did all of those later model parts work on the 20r? i guess the right plugs for the 81/82 harness it would make sense..

 

yea, i think in 81 they changed harnesses. one thing to watch for is the alternator, they changed the order of the 3-prong plug several times, try and find one from the same year as your harness

 

yea i kept my harness out of the 79 which is completely different..was just hoping to use the same short block off my other cab..now i have to go buy all new peripherals to make that 20r run..

 

going to the yard today to get my coil, igniter, distributer etc..anyone know if 81-84 2wd 22R accesories will work on a first gen 20R motor?

 

I was told by Toyota that for my 1983 pickup, the only ignitors that will work are from like 6/82-8/83 or something stupid like that, so...if they know what they're talking about, some of that stuff may be very year specific.

 

ok so now considering full 83 22R swap into her, all necessary accesories should be coming with it..
