I know. We’ll paint stuff soon.
At the end of the day, I was dying to see if anything would actually power up and switch on. So I grabbed a battery, some terminals, and clicked the ignition over. Awesomely, the sub tank dash light comes on when switched and the odometer powers up.
I really wanted to see if I had plumbed the solenoids correctly, so I checked the sub tank switch.
And then I realized that duh, the transmission harness was connected, but there was no engine harness in between it!
My theory is that with no power to the solenoids, the default setting will be fuel flow from the main tank to the lines. When you energize the solenoids by pushing the sub tank switch, you give 12 V to the solenoids which will route fuel from sub tank to motor and back. But I’m going to have to wait just a little bit because I sent my engine harness to Australia to have the FTE harness built.

I didn't know there was a workbench in there!

Kelly, there may be MORE THAN ONE.

did the sub-tank light was flashing after some seconds of switched on?

I had a long story during adding stock sub tank to @wardharris fzj79. I was missing this guy:
But then I took me too much to figure I need this too:

It isn't that long ago that my 15B was sitting on a pallet too.
I will be watching for your efforts with this. I hope it goes well for you too.

@Meshal - no flashing, but also no solenoids attached! @rick_d just sent me that flasher information this morning, too!
My harness is 2001 HZJ79 and the body is 3/2009, so there are some known differences - A/C thermistor and blower motor - but most stuff seems to match.
I am starting to work on populating the harness with relays and am having a hard time figuring out where the starter relay goes. I have the glow relay on the driver's side fender well just before the fusible link... but not starter relay plug anywhere that I can see. It is a bit of a mystery. Does anyone know if it fits on the engine harness 82121-6A131? My harness is in Australia.

This look correct but is it?
If you have a buddy in Dubai the buddy could go have a look at the HZJ79 project I'm working on. Near as I can tell it has not been modified. Neglected, but not modified.
The harness in the engine bay has not yet been touched I believe. I am not in Dubai at present.

Mostly yes, the location of the plug is behind the stereo. The small relay is in the right corner of the dash.

@Meshal I have the dash instrument and AC harnesses. I see a couple of extra wires on the parts diagrams…. I hope I don’t need any more wires.
While we are at it, do we know where the diff lock switch is on the driver’s side?
Is it a 16 pin sub harness like the 80 series or is there a different harness just for the diff lock switch?
I need to look up the pin out diagram for the 79 versus 80 locker actuators. They are both six pin connectors, but different shapes. The 79 diff wire has a separate 2 pin connector, too.

I looked again today. There’s just no damn spot on the harness here.
I am thinking that it HAS to be on that engine harness.

Oh man. It’s HERE.
A completely plug and play engine harness to run the FTE. Built by Mick Wallin in Australia. I sent him a 1HZ engine harness and he modified it extensively, then added his standalone FTE harness.

OK. I got the wiring harness laid out in the truck today. It’s hard to get good pictures, but I’ll see if I can describe it:
The modified engine loom plugs into the main cowl harness at the left fender just in front of the firewall. This is a direct pass-through to the transmission harness. Mick’s FTE engine loom plugs into this harness, runs the engine sensors, and then passes from left to right along the firewall. I drilled a 60 mm/2 3/8 inch hole in the firewall below the existing cowl harness firewall grommet. I then placed the ECU inside the glove box at the far right. I passed the pedal loom on top of the A/C all the way to the pedal box. And that’s all I had time for today.
