I don't have a callout for the plugs, but the way I reintegrated my painless into the Toyota was the GM way, both the blinkers and the hazards get their own flasher. It's easier to integrate that way, instead of running flasher power first through the hazard switch, then to the blinkers.

How many circuits is your painless? I'll dig out my notes if we have the same painless harness. I have the 21 circuit harness.
Thanks for the response. I have the 21 circuit harness. Electrical wiring is not my strong suit but I will look at how they call out the GM way in the manual. I am hoping to use the toyota switches if at all possible but it may not be an option. Any help you might provide would be greatly appreciated.

You can 100% keep all factory toyota and integrate into the GM. It shouldn't be super difficult. I'll pull up my notes.
 
Painless wiring has a instruction manual for wiring up a land cruiser. I used a fuse box mount from BTB. Things get kind of weird with the hazard switch and turn signals. Lots of people on mud have been down this road before! Search out the info. If I can do it you can. Looking at what you have done on this build I know you can do it. The biggest problem I had was when I figured it out. I would walk away from the project fo a week or two and have to figure it all out again. When you get in the groove don’t stop. Your truck is looking real good.
 
Alright, hopefully this should help. I'm not sure which year harness you have, but the idea should be pretty similar. This is for a later-model 40, but there are plenty of manuals here on mud for diagrams.

Igniting wiring if you want it.

Hazard and flasher. If you are going the toyota way, you are running both through a single flasher, and combining the outputs. If you go the GM way, you run a flasher for each one, and then eventually combine outputs for both sides.

Dangernoodle you are the man! All the info you posted in one place too is awesome. I spent many countless hours to get all the info you posted. I am installing vintage air right now. I only work on my rig in the winter months so you guys are getting me fired up. Good job!

What manual is this? Pic of front cover?

Glad to help. My vintage air was pretty quick to install. The only hiccup I ran into was I crossed one connector, which was an absolute pita to switch blind when fully installed. Don't be like me. Check your connections first. Figured that out the hard way when I couldn't get my heat to work at Cruise Moab when it was snowing and in the 20s, and I had only my bikini top on. Not the most fun.

Dangernoodle,

Thanks so much for digging this info out and then taking the time to post it. This is exactly what I was looking for and it dumbs it down so even I can understand! Thanks again!

Not a problem. Glad to be able to help.
 
Been a while but there has been progress. The wiring is complete and the glass, exhaust and seats are in. I have a little winch and radio wiring to do yet and I’m waiting on some paperwork from the state and I should be good to put it out on the roads and trails to figure out final tire size.

What fishplate thickness did you use?
 
I used 1/8 inch plate for the fishplates. That is close to matching the thickness of the steel the frame was stamped from (its metric). I thought about going heavier but an automotive engineer friend of mine encouraged me not to do that because the fishplates would not flex the same as the toyota frame and would actually cause cracks. This particular person has cut and extended tons of jeep frames and so I figured he had a pretty good idea of the engineering concepts. Certainly beyond my understanding.
 
I realized there are some details that I probably should have posted as reference related to the modifications to the radiator bracket for use with the FJ80 power steering box. As you can see I had to relieve the radiator bracket and then weld in new support structure. I used 4130 chromoly for the modification for extra strength.

Wow.... did the exact same mod in my 1Hz swapped fj40. Wish I'd seen yours . Would have been easier than having to figure it out on my own.
Enjoying your build !
 
Nice 406 Case Unimog! I enjoyed reading thru your 45 build.
Thanks. The 406/MB4/94 has been a great rig. We mostly use it as a plow but we have seeded fields with it, graded roads with it and it is set up for a backhoe. Just need to find one in decent condition to drop on the back.
I have been running this rig around on old worn out 37's to see if the tire size actually works. As it turns out, the size is perfect for this build with a spring over. I need to play with the bump stops however or I suspect I will need to cut the bed.
