So I am in the middle of my trying to trace down all of my wiring from my 22RE harness and the doner vehicle which is a 1997 4runner M/T 3.4. I have been researching for several weeks and have the 3.4 BH plug to ECU labeled which apparently is referred to as E8 in my EWD.

I'm having a hard time trying to track down the two plugs in the 22RE body harness that plug into the 22RE engine harness. I believe they are referred to as IH1 and IH2. When I pulled my TIS information, there was no information available for my 1987 4runner regarding plugs etc. Does anyone have a diagram of these plugs?

 

So this is all going into my 1985 toyota truck/truggy. However, I have aquired a 1987 4runner with a good harness that is not all hacked up to bits by previous rednecks and their "wiring" of misl things or cut things out because they don't work.

My doner vehicle is a 1997 4runner with a manual tranny.


I'm trying to figure out how to tell what my 4runner IH2 and IH1 plugs are which come from the body harness and plug into the engine harness. I stole the below image from google/this site as these are the plugs I am needing to identify the wires for on the 87 22RE

 

I am not running A/C, Cruise, ABS, MANUAL

While matching up the wires for II1 I don't get any wires that I need to keep, is this normal?

II1
1) B/Y - (ONLY FOR AUTO)
3) Y/G - ASSOCIATED WITH CRUISE
7) B/L - ABS
8) R/L - ABS RELAY
9) R/L - DATALINK ABS

 

FOR II3 plug which is from the 3.4 body harness to the 3.4 engine harness connector (same as II1) I get the following things I need to keep. I still have a few questionable ones.

8) B/R - from ignition switch (also feeds to ECU)
15) B - have not seen on my EWR yet
16) W/L - EFI Relay also on E8-12 to ecu
? 18) BR/R from D7 data link connector 3
? 19) R/Y - I don't think I need this one, it says neutral switch then another one for the backup light switch. I believe it may only be for an auto

21) Y/R - water temp sensor - will go to gauge cluster
22) G/W - Oil Pressure switch to gauge
? 24) BR - this is some shielded wire. I beleive it goes to the OBDII plug if I am not mistaken?

26) G/Y - From COR and also tires into the ECU at E5-14
