I have most of the wiring done. I wired it the way it says to on supracharged. I still need to figure out what wire is for the tach. Also I have to run the green wire to the green wire on the airflow meter right? If there is anything that I should know on the wiring let me know!

 

Ok let me tell you what I have done to help out a bit.

B+ power
white/red (truck) IH1
black/red (supra) B1

Comp power
black/orange (supra) B1
black/red (truck) IH1

Starter
black/white (supra) B1
black/white (truck) IH1

oil pressure
Yellow/black (supra) M1
yellow/green (truck) IH1

Engine Light
Gray/green (supra) M1
Dark blue (truck) IH2

Speed sensor
Pink (supra) M1
green/blue (truck) IH1

This is what I have done so far. On supracharged they say I need to use the black wire for the Tach and there are two black wires on the m1 connector. Also they say I need to use the green wire for B1 and tap it into the green wire on the AFM. So I need a little help to figure this stuff out!!!

 

no 7m swapers got a clue?

 

Sorry man i cant help you. But try hitting up corax with a pm.
He seems to have the best know how of the swap, but i dont think he is on very often.

 

Ok thank bro!

 

np. I do what i can to help, but i cant say that wiring is my strong point

 

well Im a electrican by trade but auto wiring is a different ball game lol

 

well today I have been going threw the factor service manual for the supra and truck wire harness and let me tell you if you get the sheet off of supracharged and try to use it the some of the pin outs that he has on there arnt the right ones. If you are doing this swap I would def get the wire diagrams!!!

 

I don't have a working CEL in the dash for some reason yet (used a test light and alligator clips to check codes), and your colours seem different than my 87 for that, but it has started and has no codes. Green from the supra afm to green on the truck afm works for me, did it under the hood...I also have the same condition as Roger Brown, where the fuel pump only starts after cranking for a few seconds, so it might have been a pre-existing condition. I also grounded the white/black on M1 (the one on the driver's side front where you go to the battery with a 7.5 fuse) to get the check connector working properly. Tach wire was in the igniter harness under the hood on the supra I believe, but I haven't hooked it up yet. You'll need plugs from the 22re harness for reverse and 4wd indicator lights.

This has worked for me so far, but your truck may be different as it's newer than mine.

 

yeah I seem to be on the right track! The wire that your have to use with the 7.5 fuse is a wire coming off the c1 connector I do belive. I found that there are a black wire on the m1 and a black wire on Ih2 in the wire diagrams these two black wires are for tacho meter!

 

also witch wire are you using to tell the ecu you are starting the engine. It says to use a small guage black blue on the m1. I dont have that wire
