Having done a 3.0 to 3.4 swap, manual tranny, the first thing I would do is get the wiring diagrams for both vehicles and start to sort those out in your spare time. Find that at this site:

https://techinfo.toyota.com/techInfoPortal/appmanager/t3/ti?_nfpb=true&_pageLabel=ti_home_page&SMENC=ISO-8859-1&SMLOCALE=US-EN&SMAUTHREASON=0&SMAGENTNAME=%24SM%24mT%252bGLraBu9CwUVnZg4mEDzB2kysT90hgbwsWgdZzNOc%253d&TARGET=%24SM%24https%3A%2F%2Ftechinfo.toyota.com%2F

I assume you have a full wiring harness from the donor and the matching ECM. There is a lot of info on Mud and Yota Tech. Terry

Thanks Terry,
I do have the entire donor vehicle but my problem is that I am going from a 22RE to 3.4. There is a lot of info on the 3.0 swap but I have found very little on the 22re swaps.

I will save your links in my research folder and most likely use them a lot. I am not an electrical guy so that really hurts me. Need to stay positive and take it slow and easy.

Thanks for your info again and I may have to lean on you if I run into problems if that is OK with you.

I will help where I can, but you really need to search the forums for anyone who has done the 22re to 3.4 swap. T

Mike Caskey did my 22RE to 3.4 swap. Not as simple as a 3.0 to 3.4 by any means, but the wiring should be about the same. Basically you are adapting the 22RE body harness to the 3.4 ECU connectors, most of the connections come from the 3.4 engine harness. I hope you have an auto ECU and harness with matching auto tranny, that should make things possible. If not... :eek:

I would STRONGLY suggest getting ahold of TheFatKid for electrical assistance. The mechanical part, ... have a means of holding the engine and tranny in position, more or less, and build motor mounts and tranny mounts to fit, as needed. A 1" body lift is STRONGLY recommended. It is possible without it, but it is 5x as much work. Mike did mine without it and it turned it into a real money loser for him. He must have pulled the motor and tranny in and out about 5 times trying to get everything to fit. When I finally rolled the thing, I put in a 1" BL and suddenly there was clearance everywhere. Especially behind the motor.

I know you will want to go hammer and tongs to get this done, but Tom, believe me, taking your time will take far less time! :lmao: You can't afford the time it takes to hurry. You'll break in a hundred ways at CM and have a no good very bad awful time of it.

Hope that helps!

I'd e-mail ORS and see if they still have some of those brackets left over for such a swap. Mike had tons of the frame brackets lazer cut and I know he moved a ton of that stuff out to his house/barn. He does look at his ORS e-mails still and is building some harnesses and stuff on the side.

I can vouch for Mike's work as factory quality. There's your easy button, Tom.

if there way any way I could get Mike to build me a harness, I'd pay for it no questions. Your swap will go easy if you can get that done. The physical part of it is easy.

Ah, decided the black chassis wasn't worth the work eh? Too bad, it had potential.

Brian, correct me if I'm wrong, but if Tom pulls the dash apart on the black truck, and pulls his dash apart, can't he just transfer everything over? He has to rip the dash out anyway.

That truck has an ORS harness in it.

Thanks, I plan on doing that. I was hoping to keep the harness I have now and alter it for the 22re set up. I don't think I need motor mounts but could be wrong.

RockRunner

I would like to know that too. Biggest problem is that ORS is still charging nearly twice as much as Brian or another guy in Denver. I have tried to get a hold of him but it has been hard also.

Quit stressing and get to work! Mounts are freaking easy and once you get the wire schems from both vehicles in front of you with a note pad you'll wonder why you wet your diaper!

I is easier to keep my suspension on my truck and and swap motors. I am trying to figure out what I may use it for got some ideas. What is it that is different in the dash area between the two.

My problem is that I can't find to much on 22re swaps, most go to the 3vze and that is no help.

Any word on the other parts Isaac? I will need to swap the tank hoping they upgraded the fuel pump in there for the 3.4.

Here are some notes that may or may not apply. This is from the 3.0 to 3.4 but it gives guidance on what to look for. Terry


3.0L(3VZE) To 3.4L(5VZFE) Engine Conversion

3.0L Parts Needed:
Motor mounts
Bell housing
Clutch fork
Throw-out bearing
Radiator/shroud/fan
Oil pressure sender
-The 3.4L mounts sits at different angle although the bolt pattern is the same. I think the bell housing is the same for both but not positive, same for T/O bearing and clutch fork. The 3.0L fan will bolt to the 3.4L fan clutch, I think all the 3.4L radiator parts will work also but not positive.

3.4L Parts Needed:
Engine ECU
Engine wiring harness
Clutch/pressure plate/pilot bearing
Flywheel
Intake system with MAF sensor
Radiator hoses
All sensors including both o2 sensors, etc
Evap box
All accessories (A/C, PS, alternator, radiator fan clutch, belts, etc)
-The 3.0L evap can may be used with the 3.4L evap can sensors to save space in the engine bay. I will get some pic of how to do this.

Universal Parts:
5-Speed tranny (R-150F, same manual tranny for both motors)
-At this time I have little info on swapping in an auto tranny, it can be done and at minimum requires the 3.4L auto ECU and 3.4L 4-speed auto trans. Although the number designation given the 3.0L tranny and the bolt pattern are the same as the 3.4L tranny, they are not compatible electronically. Off-Road Solutions is now offering kits and instructions on completing this swap.

Additional OEM Parts Needed:
2WD T-100 Oil Pan
2WD T-100 Oil Sump
2WD T-100 Dip Stick & Tube
-I understand that if swapping into a 2WD truck the stock 3.0L oil-pan can be reused with some modification.

Additional Custom Parts Needed:
Conversion wiring harness (To adapt engine harness to body harness)
Flex Fuel Line Adapter (To adapt engine fuel lines to body fuel lines)
Battery Tray (Opposite side of 3.0L configuration)

Body Modifications:
2" body lift to accommodate additional height of 3.4L intake manifold
-Hood can be cut instead, I will make a template of the hole and post it soon. Also a scoop or cowl can be grafted to cover hole. I believe toyotafiberglass.com is making a bulge hood for this.

Known Bugs & Solutions:
The tach, cruise control and A/C all will not work because the 3.4L uses positive pulse RPM readings and the 3.0L uses negative pulse to control these devices. Also the stock oil gauge will fry due to the 3.4L sending a higher voltage.

Tach Solution:
Solder 10K-OHM resistor between two contacts on back of*the stock 3.0L tach. The links below are pics of the tach mod for both 2nd(84-88) and 3rd(89-95) gen trucks.
Tach Pic 1
Tach Pic 2

Cruise Control Solution:
Adapt 3.0L cruise system or ideally install complete 3.4L controls and wiring

A/C Solution:
You need the electronic card from the 3.4L A/C cooling unit located behind the glove box in the donor vehicle. With the 3.0L configuration the card receives a signal from the negative side of the ignition, in order to work now it will now need to receive a positive signal from the ECU instead. You will need Toyota wiring diagrams to figure this one out.

Oil Pressure Gauge Solution:
Voltage Differences Require Use Of 3.0L Oil Pressure Sender To Prevent Damage to 3.0L Gauge. Or you can use the 3.4L gauge. Some people claim to not have a problem but more than not have fried the stock gauge.

I am, starting Saturday;) I just suck at electrical stuff and don't want to blow up an ECU or whatever else I can blow up. I can blow electrical stuff like the best of them.

Secret: Don't hook up the battery until you check your circuits first! ;) ECU's are actually protected quite well from reverse flow but little wires have issues with 500 amp shorts! Caskey make a great harness but unfortunately all the wires in it are red and/or black. That frosts my arse when someone does that!

RockRunner

Terry thanks so much for the links, there were a few new ones in there I did not know about so more reading to do.

Kevin, if I felt better about the electrical I wouldn't worry so much but since I am a noob when it comes to that I worry. Funny you mention the red and black wires, my E locker wiring was all done in blue and black and all taped together. He blamed it on a kid that worked there. For the money he charges for a harness it should be color coded, at least that is what I think.

Couple of Points.

The fuel tank I will be bringing you has the lines for the body as well. The pump is not just a 3.4 pump, but a high output walbro pump to keep up with a supercharger. You will not have issues there.

Here is my point:

You seem to want to mess around with all this wiring.

If you simply pull the dash, use his cluster, and dash wiring, you can make this work.

The engine wiring unplugs from the computer and pulls through the dash in one spot. It will litterally take you 5 minutes to do this. Then you can pull the motor out of the black truck.

The differences between years is relatively minor, but you still need to go through all the pinouts. it is much easier to simply pull all the harnesses out from behind the dash, and swap them between trucks. You could get all of the wiring pulled and swapped in a weekend.

You do need motor mounts as you have to move them, but you can fab them easily. It took me an hour to do the ones on the black truck, and I was messing around with my dimple dies to boot.

Assuming you did all that, you could honestly have this done in a month.

You don't need another fuel pump. The 22RE fuel pump is fine for a 3.4. For that matter I am running it with the blower (with stock pulley, mind you) and have no starvation.

Yeah, I forgot Mike had red and black wires all over. I agree that sucks. He may have corrected that now.

Didn't know you had the 3.4 conversion truck to work off of. Follow Ike's advice. The body harness may not quite match but that should be easy.
