Calling all wiring gurus or anyone who has done an "HJ62" project.

Tofudebeest · 01-11-08, 01:52 PM

See the most recent posts to my build thread for current details: http://forum.ih8mud.com/60-series-wa...fudebeest.html

In short, this is an 8/81 Aussie HJ60 (RHD) powertrain (new H55F installed last year) into an '88 FJ62 (U.S.). The current debate is on regarding which harness to use, with many opinions floating about, none convincing either way. I'm a wiring virgin.

This CAN NOT be the first HJ62 (5-speed) ever, or even on Mud)...

Anyone in OZ???

I would leave the gasser harness and run new wiress for those litlle things that the 2H needs to run ..

Tofudebeest · 01-11-08, 06:40 PM

That is what I am thinking too.

I think your main obstacle is the RHD vs. LHD differences in the looms. For this reason, I too am a vote to create a "sub loom" from the RHD donor and make a clean installation alongside the FJ wiring.

Your biggest pain is going to be to wire the edic if you are still using it. When I did my 3B FJ60 conversion I used the FJ harness. I had an edic and and edic relay with the plugs and a short amount of wiring on each. There are several wires that are direct between the relay and the motor which are easy, 4 I think on my 12V, and there were 4 others to wire in for keyed power, battery power, ground and starter solenoid.

I also had to wire the tach and the alternator. The alt was easy because I had a plug with some wire. Just cut off the 62 plug and wire in the plug from the hj harness.

The engine I used came out of an FJ62 (converted to 3B). All you are hooking up to the 5 speed are the reverse and 4wd indicators which also exist for the auto trans. When I got the 62 they even wired the 3b tach sensor to the 62 tach and it appeared to be working correctly.

I dont see how RHD vs LHD is a concern.

I would run the RH diesel wiring harness down the LH side of the FJ62 and swap the electrical items from the HJ60 into the 62.
Minimal extensions,no mods,just plug and play.

Rosco, no offense (really) but without details, like lynchmob provided, short and sweet preferrence comments (whether I like them or not) are not particularly helpful. Flatly stated (though well-meaning) opinions of taste are what has gotten me so confused and why this thread got created in the first place.
If anyone knows of someone who has ripped out a diesel out of a RHD and put it into a LHD (the more similar to my swap, the better), get them to chime in, please.

As for my EDIC, I was under the impression that if you wheel, and if you expect to ever roll backwards (inevitable) you best keep your EDIC unless you like fires under your hood. If you opt out of using it, you might be really, really sorry.
I found this: "Within a two month period two underground fires on Toyota 4 x 4 Land Cruisers were reported. In each case the fire was caused by the engine being driven backwards, as the vehicle rolled back after stalling on an incline, while still in forward gear. This caused the airfilter to ignite due to the combustion cycle being reversed. Both vehicles were HJ75’s with 2H engines. The 2H series engines are originally supplied with Electronic Diesel Injection Control (EDIC) motors that prevent the combustion cycle being reversed. In both the reported incidents the vehicle EDIC had been removed. Where any HJ75 Toyota Land Cruisers equipped with 2H series motors are in use, it is most important that the Electronic Diesel Injection Control motors are fitted and operational. These motors are part of the original equipment and prevent the diesel engine operating in reverse. Failure to ensure that the EDIC motor is fitted and operational could result in a fire on the vehicle. Toyota agents advise that Land Cruisers produced after October 1990, namely the HZJ75 models, with the 1HZ series motors, do not have the same potential problem. Any fire that occurs under the bonnet of a vehicle is difficult to extinguish and caution is required when attempting to raise the bonnet, as flashover may occur, or the battery may explode.

Interesting...

But, there are threads I've been looking at where ditching the EDIC can be done *somehow* without causing safety problems...

Doesnt need a long winded explanation ,it was intended to be simple. The harness worked on the RH side ,so why shouldnt it work on the left?
My intention was to unconfuse you

The HJ75 fire under the bonnet is a repost of a post of mine from 2 years ago
