I have a 99 EWD for my donor which is great. All the connectors are shown and labeled.

My 88 FSM EWD's are pretty basic. No images of connectors or reference to them.

I have most of my wiring labeled and ready to go except for two connectors. I started to just go through the schematics and look for the wire colors but, Toyota likes to use the same color in different places.

Hopefully someone can help me out here. Here is one of them. Has 10 wires.



This one uses 8 wires.



This one plugged into the ECM and was easy to figure out with the schematic.

 

The plug in your 2nd pic (8 wires) appears to be plug N3. Where did you get your EWD's from? I got mine from TIS and the EWD for the trucks were pretty basic, where as the same year on a 4runner they had more information.

 

I have a complete FSM with the EWD's in the back of the book. Not accurate. Enough to get me by.

I have been pretty much physically verifying the wires on the 88 side. The 99 has excellent EWD's.

I was hoping somebody had pin out's or whatever so I could compare my wire colors to the pins positions in those two connectors.

I "THINK" I have them figured out but, if anybodys got more info I would appreciate it.

 

You could try sending theMonch a pm. That's how I identified the plug by his write up. His swap was with a 88 4runner.

 

I looked at every thread and sticky on this site. Found a lot of info but not all.

What makes mine a little more difficult is 88 was a unique year as far as electrical. 22RE anyway. Not sure about the 3.0.

My truck was built Nov 87. Right about the time of some changes. Maybe why my schematic doesn't exactly match my truck.

I'm learning a lot doing it the hard way. I think I pretty much got it............I hope!

The tough part is when I have the same color wire at different pins in the same plug AND in another plug AND no connector references. Just a schematic with dots where the wires connect. Process of elimination and verification with a meter. Very time consuming.

The 99 EWD references the connectors in the schematic and has diagrams with the wire color and pin numbers for both the male and female side. Made it easy.

Thanks for the replies.

 

I didn't notice you had started with a 22re. I know every swap is different, but looking at my wiring there is almost no difference between the 3vz and 22re pins or colors.
Have you looked at theMonch's 5vzfe swap wiring pdf? It might help finding wires on the 88 side. It shows the plugs, which wires go where and wire color and function. He used 1997 t-100 but some of the wires were on same as my donor(2000 4runner).
