First off, a quick link to an earlier thread, but related to this swap.
https://forum.ih8mud.com/diesel-tech-24-volts-systems/239824-3b-cradle-edic-wiring-question.html
With that part done, I decided to try to swap the 3B into Dad's 1979 FJ-40 in November.
In October, I took it on a little trip. To Northern NM/Southern CO to see the Aspens.
Tonight, with the help of Dad and Mom, we started taking stuff apart.
The hard top is OFF.
I have to head off again to work tomorrow for a couple days, but when I get back I've got 4 days off before I have to go back to work (and I'm thinking of calling in sick for at least one trip this month). In that time, I'm hoping to pull the 2f/H42, and get the tub off of the frame. With any luck, I'll also find the time to get the 3B installed in the frame and the parking brake added to the split-case.
We've got a crossmember and frame mounts for it from a BJ-42 with the 5 speed, so that part is taken care of, along with BJ-40 motor mounts and isolators.
Here's the parts I still need to source to make this work:
The hardest one here seems to be the EDIC relay and wiring. I'v got P/N 28590-56090 from Toyota, along with the Denso numbers for it too, but I have yet to find one. At the moment, the engine will be installed and I'll just open the hood and have a helper crank it while I hold the fuel control to "overinject" or something. It'll be annoying, but at least the truck will be driveable while I source a relay and wire it up. The part is common to the BJ-60 as well, so you Canadians please keep your eyes open for me.
Especially if you see one being parted. I'm also hoping to get the foot of wiring harness from the plug for the EDIC motor and EDIC relay to make my wiring job easier.
The engine came from an Australian BJ-73 that SOR brought in, and Dad bought from them about a year ago. I believe it's between an 1984-1988.
The truck is currently bone stock, with a smogged 2F that runs great (just uses too much fuel IMHO), and an OME 2.5" lift and 33x9.50 tires. I think it'll be just fantastic with the 3B/Turbo and 5 speed.
My plan is to just get the engine and transmission installed and working, and then maybe start working on the little bit of cancerous rust on the truck, but to leave it for a year or two to really disassemble and repaint and everything. But we'll see. I just want to get the engine in (and avoid working on mine for the winter, so I can save $$$ for ripping my HJ-45 into a lot of little pieces next spring).
Updates when I get back to working on it in 4 or 5 days (depending on when I get home). But probably questions from the road.
Guys that have done this already: am I missing anything?

Here's the parts I still need to source to make this work:
- 5 speed/engine rear isolator
- EDIC relay and related wiring for this engine
- clutch slave cylinder
- air cleaner that will work with the Safari turbo that was already installed on the engine
- driveshafts will have to be made/altered (once engine/trans are in)
- Radiator: should I just have the FJ-40 radiator reworked to move the inlet and outlet, or should I order something?
- Pyrometer, Boost Gauge and Water Temp Guage will be added
- Must get the 3B pulley and plate for power steering, as well as mount a PS pump (the truck has factory PS)
