84 22RE to 5vz
 

Hey guys finally doing this swap. its well underway but im trying to plan ahead. i am completely lost as far as the wiring goes. i have no problem fabbing the motor mounts and any of the physical work but the wiring im 100% lost.
my truck is super rare with a factory 22re as an 84. it runs a completely different wiring harness then the 85+ trucks, only has 2 plugs at the ECU, not 3. not sure how that affects things for the swap.
the 3.4 is out of a 97 4runner i believe. i have the ECU that went to the 97 but im mating the motor to a 2wd R150 trans. at some point this all needs to be smog legal but right now i just want to get it running.

question 1: anyone have a pin out of the ECU?
i dont have a chassis harness. so i dont have anything for the last plug on the ECU. trying to figure out if im better off buying a plug and making my own harness or finding a stock one to cut up.

2: there are the plugs on the engine harness that plug into the ECU, but there are i think 3 other plugs. what are those for?

i have wiring diagrams from ondemand5.com but i suck at reading those things.

go to toyotatechinfo.com get all the ewd's for the 3.4. You can buy a the plug from the dealer... and you'll need to get the leads for it two.. the r150 trans? as from a v6 3.0? if so.. find an engine harness from a manual 3.0 you'll have a plug on there that will work for your ecu and you'll have the wiring for the trans on it as well.

yes, the trans i was told was from a 3.0 t100. besides the plug for the ECU what other wiring is there needed for the manual trans?
thanks for the help.

also unless im completely dumb (maybe) toyotatechinfo.com doesnt exist.

did you mean the TIS site?

yeah i ment the tis site. If you get a 3.0 engine harness say... from that t100 you'll have the trans plugs and you'll have a plug from the ecu side of the harness that will work for the missing plug form the 97 assuming it was a manual trans engine... take a picture of the ecu/plugs on it.

ok thats the part i left out, the ECU i have is for an auto. it is matched with the motor but the trans is a manual and from a different truck. eventually i need to get it passed the referee station so there cant be a CEL but for now i just want it to run.

does the chassis harness off an early 93ish (not sure) auto 3.0 4runner help me at all? there is on at a local pick a part i could go try to get off. any major pain to get off?

all the "good stuff will be on the engine harness side but being the motor is auto... don't think my idea will work.

so is there anything worth getting off the 3.0 4runner? all the wiring was complete.

thought i would post an update. havent gotten much of the wiring figured out but i have been working on other parts of the swap/ truck rebuild.

2wd stuff, i know not common to most of you guys lol

got it running today. drove it around the block with no major issues other then a major thorottle lag, but thats not a surprise because i dont have any of the vacuum lines hooked up or have an exhaust or 02 sensor.
does anyone have a good diagram of the vacuum lines and all the coolant lines?
thanks
