Hi

I'm starting a 22r to 22re swap on a '86 extended cab. The donor is a 1985 4runner with 37000mi (late-mid '80's crash victim that sat since).

I did a tune up on the 22re (its still in the runner) and want to get it started before i pull it and put it into the '86 truck. It cranks fine but there is no fuel coming forward. I've ruled out the MAF switch, and the main relay, I did jump the diagnostic plug on the drivers side. I tried all this but the pump is dead, i gave it juice by hooking up a 12v batter directly to the input plug going to the pump, nothing. So I pulled it. Whoaaa there was a lot of rust in the tank... The pump is all corroded and definitely needs to be replaced. Since there is all that rust in the tank I don't know if I want to even swap it over to the truck like you're supposed to.

My question, is it easy to put an inline pump on the pickup that will wire up to the efi wiring harness? if so what kind of pump is recommended.

Also if there are any heads-up pointers on this swap in general let me know, i'm new to this. My plans is to strip the full wiring harness from the '86 and put the '85 22re and wiring harness into the truck.

I'm assuming all the accessories will be plug n' play (wipers, heater motor, lights ect). Does this include the ignition? or do i need to bring that from the runner as well?

A lot of questions... I know. anything will help!

cheers
 
I think you will want the ignition stuff from the EFI. It's only a few bolts to pull the whole ignitor off the fender...

Doing an inline pump sounds like a good plan. Just make sure it's near the pump, they push well but don't pull so good usually... I think the PSI needs to be around 45, but double check the FSM to see what it needs.

We'll want pics! :D

pics didn't load. So I just pasted my facebook album.

It contains pics from both projects.. What a clusterF#@k:hillbilly:

i am not sure if the 4runner tank would work in a pickup anyways, i do know that the pickup tanks will not work in the 4runner, i tried that! but if you want to change tanks just look in u-pull it yards.
 
Can anyone give me a quick run down on what i need to do on this swap, i've been reading up on it and i'm confused about the wiring harness.
The question is do i strip the whole 86 harness (all of it) and get the whole 85 harness into the '86? Or is there parts of the '86 harness that i can leave in there and continue to use? is the cab harness and the engine harness separate?
 
i would strip the complete harness out of the fi truck, Toyota changed the size of there connector in 86 i believe, it was 86 any how, you will figure it out once you start into it, but it is best to have every thing you can off the FI truck and i would not get rid of any thing till you are done.

Hi

thanks for the tip. So i just finished reading 7 pages of the FAQ on Pirates,22R to 22RE swap FAQ - Page 7 - Pirate4x4.Com Bulletin Board (what a jumble of opinions!, a little hard to follow).

I think you're right, i'm just going to strip the carb'd truck and put the complete EFI harness (including lights, heater motor and all accessories) into it. I just hope that the tail lights and ignition plugs all match up. I will also cut out all the sr5 accessories from the efi runner (the inclinometer lights and electric window wiring ect). Or I could even swap the runner doors over and have electric windows.....

I guess if i have to i can even swap in the efi stuff from the steering column (wiper switches, light switches, and ignition key). Does this sound like a fair assumption?

I want to tear into this today:clap:
 
yes it does, look out though, the 4 runner's tail lights are ran on the inside of the truck, the pickups tailight wiring goes out under the pass side seat, so you will have some splicing and such to do, you do not have to cut things out of the harness, if you are not going to use it you will just have an empty connector.
 
Update

I have the passenger fender clear of everything and the engine harness out, the drive shafts off, and the transmission and engine loose (its hanging on the crane! Tomorrow i'm going to remove the front clip (crane won't go high enough to clear oil pan). Boy these toy's are straight forward to work on (the last engine i pulled was a OM617 mercedes turbo diesel). Took me twice as long.
 
Long needed update:

So this project didn't get going right away, I've been busy with other things (see 1981 pickup getting om617 here on mud).

Yesterday I took out the whole engine and cab harness out of the 86 and put in the 85 harness. The following plugged right into the existing 86 accessories:

Steering column plugs (ignition, lights ect)

I swapped over the brake and clutch sensor from the 85 and plugged them in. Throttle sensor was the same.

All heating blower plugs seemed to all match.

door sensors

the front light harness from the 86 plugged right into the 85 harness.

I realize now that there are great many plugs on the passenger side by the ecu that are sitting empty now. They must be for power windows? I'll post a pic.

Same thing goes on the drivers side I have about 3 or 4 that i still need to figure out.

I'm going to go with a inline fuel pump. What is recommended for getting a signal to the ecu for fuel? I still have the 85 intank pump and plugs.

Next i'm going to splice the truck rear light harness into the 4runner 85 harness. I noticed that the runner has a couple of extra wires, what are the differences?

sorry about the long post
 
why not just use an EFI tank and stock fuel pump? you already have the wiring itll just plug in

the extra wires on the rear chunk Id assume are for rear window

did you swap the fuse box on the drivers side?
 
I've heard using the efi tank from from a 4runner won't work in a pickup because of filler neck location? correct me if i'm wrong?

Everything electrical was swapped inside except heater stuff, and a sensor or two.


Update for work done today. I got the engine wire harness back on the engine and the engine in the engine bay, tranny was already in the truck, lined up very easily. I was quite surprised. I also put a new exhaust manifold gasket on before putting the motor in. Cleaned all the electrical plugs as well.

Tomorrow i'll get the rad hooked up and continue trouble shooting more wiring stuff.

Can anyone recall what model ford inline fuel pump people like to use for this swap? If i have the hard fuel line out of the 4runner should i swap it in?

pics tomorrow
 
I'm not very good a keeping the updates going.

Anyways got the rad hooked up, starter, vacuum lines, power steering, and ignition today. Pulled the 4runner tank and 86 tank and concluded that the runner would bolt right into the truck, except its too rusty to use and the filler tube would be stretched and might need an extension (this was all today).

I still have to figure out fuel pump ect. I installed the hard line from the runner today as well. The dash is still in pieces but i plugged in the instrument panel and hooked up the battery!! it turned over without hesitation!!!!:bounce::bounce2:, and the lights, horn, signals all worked. I tried the blower but that didn't work, any suggestions why? The 86 still has the ac in it, cooler, lines, and pump but i don't know where to attach it on the 22re? the donor didn't have ac. Any suggestions? could this be why the heater fan didn't work?.

I also have a couple of plugs that i can't seem to remember. One white one on the drivers side (round with 3 pins, female), and one on the passenger side, that's in the engine ground to the battery, what does that plug into? must be a ground for something. also a two pin T style plug in the engine wiring harness (between injector 2 and 3, white, female), and another under the intake manifold that is green and only a single. I'll post pics of these tomorrow. If anyone has an idea let me know.

hi everyone

so i'm still getting after the wiring. Head lights work, but all the signal lights on the front end don't work except drivers side bumper light. Before i ask my question, is the signal light circuit in series with the rear? because i haven't spliced the rear into the harness yet. I didn't think so because the front left bumper signal does work....the signal relay is clicking fast though, as if a bulb is out..... let me know.

Next is the heating system. I left the wiring cricuit for the heater blower in the 86 and plugged it straight into the 85 harness. switches plugged in no problem, blower motor is plugged in, but what ever is next to the blower motor (big unit towards the driver) with the big green plug that divides into some other plugs has one empty plug with no home, it is a 4 prong one. There is no where on the 85 harness to plug that in. I also tried to make the blower work by using the 85 heating circuit wires only, and i noticed that it had two sets of fuses/resistors (ten amp ac and heater). I even plugged in the 85 blower motor.

The relay for the heater clicks and then pauses for a while and then clicks. this happens between the off and the first fan setting, it doesn't get worse as you turn the fan up. What does it mean if the relay is clicking?

Sorry about the long post, but i'm a total newbie when it comes to wiring. Horn works!!!
