A warning about swapping turbo 22ret in place of 22re...

I had originally thought that swapping a recently aquired 1986 22re turbo motor into a 1990 Toyota pickup (which had a blown motor) would be a fairly straight-forward affair. Boy was I wrong! I received an underhood complete harness and computer with the engine purchase. Here's the long and short of it all...
1) 1990 truck had all three plugs which plug into the computer come from the engine bay, however the 1986 truck only brought 2 of the three plugs from the engine bay and the 3rd was under dash (which I didnt receive) so I had to cut the 3rd pug out of the existing harness and make a new one. I have purchased a 1990 manual, a 1986 manual, and D/L multiple wiring diagrams from the good ole' net. These also included finding and D/L a "pin-out" diagram showing what each pin on the computer goes to.
2) Toyota changed the color of EVERY wire in the harness, so I have to go thru the entire under-hood and in cab harnesses WIRE BY WIRE!
3) All the plugs are different, so that means locating, splicing/replacing/even more wires...
4) I have never had any experience wiring a vehicle!
I'm not saying that this swap cant be done, It's just going to take ALOT longer than I had planned, and in retrospect i could have swapped in a V8 SBC and already been driving it. I thought it would be cool to have a turbo 1990 single cab 4x4, but the complexity of this swap is killing the cool factor, at least for me. I guess what I'm trying to say is not to assume that just because its basically the same engine, it's not "plug and play". Just wanted to save someone else a headache...

Just wondering... how hard it would be if you were putting the te in a vehicle from a similar year. Lets say an 86te into an 87 re.

This should be a sticky. I can't go 1 week without someone asking "I plan on turbo(ing) my 22RE...what needs to be done?".

What did you expect when you swap a engine. Heck the mechanical part was simple

Why do you feel a Small block Chevy would be much different.

That is the name of the game you had it correct one wire at a time one by one till you have the harness merged and it looks factory .

I can`t see how someone can think it would all just be plug and play But we see it all to often anymore.

To me the wiring is the easy part yes it takes time but it is simple with all the information

Look on the bright side...once you get it done you will have accomplished two things!
1) you will have a 90 pick-up with a 22-rte, that will look factory...quite high on the cool scale.
2) You will be an ace at reading and interpreting Toyota wiring Diagrams!

Guys, I'm just about to put the whole 1990 22 rte swap project up for sale CHEAP! the wiring involved is more than I can handle! The motor is mounted in the truck and I have been tryiing to wade thru this wiring mess for months....I'm soooooo done...I'm gonna post a bunch of pics in the afternoon tomorrow to see what kind of interest it will generate, if no takers l'll crush it.

Little bit of advice!
Step back from the project for awhile...have a beer or two...let your frustration subside.
Then decide. there really isn't a lot to do with the wiring. The biggest thing is you have to wire in a solenoid resistor into the injector circuit. Any resistor from 85-mid 88 22-re will work, it doesn't have to be from a 22rte. On the 86 this was wired into the body harness, but it doesn't have to be.
you have both wiring diagram manuals, the connectors are listed on the page following the diagram and it even tells you what color plastic the connector is. There is no plug and play swap, most times the colors won't match that is why you have to trace out the wires and splice them according to what their function is not according to what the color is.
You have gone this far it would be a shame to quit now! It's a 22-rte Toyota going into a 22-re toyota, really the wiring scheme of this swap is not that difficult.
Last year I built a wiring harness for my son, a 5.0 liter FI mustang engine into a Mazada Miata....at times that one was a head scratcher. My son just shook his head he leaves the wiring to me.
I mention this, because I'm trying make you see that once a person learns to read and understand wiring diagrams, the process is not that difficult.
Have a little faith in yourself...you can do this!

yeah, don't give up now. Youre nearly there. I'm trying to finish a motor swap in my samurai, it's down to the wiring now.

LIke Hadmatt said, have faith in yourself!
