Yay updates!
The bad:
The intake tube for the t100 makes the airbox hang over the outside of the passenger fender. So I called the ref and they suggested using a carb legal short ram style intake. They also said it must be for a t100 and to not modify it. They failed others in the past that tried to cheat the inspection by cutting the intake tubes shorter. It sounds like they have the measurements for the kits. K&N is the only company that has a carb legal intake for the t100. It fits the first gen but they run $350 and the heat shield is way too large. I am also opting to relocate the battery to the bed due to lack of space under the hood and I cut up the driver side fender to fit my IFS steering box.

The good:
High and low pressure fuel lines, and the gas tank vapor tube is plumbed. I reused the t100 fuel filter and lines and reused the 1stgen emissions lines and ran them under the passenger side of the truck. I would recommend doing all new lines if you want it to look super clean and/or using the original 22r fuel line and emissions pipe for the 5vz low pressure return and charcoal canister. Mine are nothing to be proud of but they will work and don't leak.

Radiator is in. I used an Ebay special aluminum 3row radiator for a 3.0. It also had to redrill the holes and space it away from the original mounts because the lower part of the radiator would hit the frame crossmember. I also had to cut part of the hood brace but not to the point it would compromise the strength. Also when using the 3.0 r150f trans, the 3.4 starter will bolt up to the bellhousing but the lower threads on the starter will have to be drilled out. The 3.0 starter bolts are run through the starter into the bellhousing, the 3.4 starter is run through the bellhousing into the starter.

Sorry for the late updates but hella progress has been made but I've been slacking on pictures.

Wiring...
I kind of did the engine wiring in sort of a lazy fashion. I opted to not remove the in cab fuse box and just removed most of the non essential things like climate control, audio, dome lights, etc. Starter circuit was 1 black/white wire that matches the first gen ignition wiring, there was the signal wire for the efi and 1 for the obd circuit and just grounded the clutch cancel relay and the thing started first time. The check engine light was one power wire from the obd circuit and one ground wire to the ECU. I dont really have pictures for this. I couldn't get creative enough to mount the battery in the engine bay so it is now in the bed and a main power wire ran to a junction block under the hood. Then I had to extend the old fuse able links to the junction block to get all my lights and original gauges to work. Still need to figure out how to mount the ECU away from feet and water.

Exhaust...
I had to cut and rotate and weld the collector tube after the crossover to get the front o2 sensor to clear the cab. Then I cut the tail off the cat and rotated it to clear the crossmember behind the cab and position the rear o2 sensor better. Installed magnaflow muffler. Basically I did not remove or add any length to the exhaust to keep it as close to original to pass inspection.

Gauges...
Removed my ashtray and installed oil pressure and coolant temperature gauges.

Fuel tank...
Ran all the lines, soldered the 22re fuel sender to the factory harness. Which coincidentally the wire colors match and works with the factory fuel gauge. Although I dont know how accurate it is yet.  Wired up the fuel pump to the t100 harness which sure enough the 22re fuel pump is the same color wires.

Power steering...
Still need to get to the machine shop here to come up with a solution to retain the 3.4 banjo bolt on the pump and run it to the steering box so I can retain the vacuum advance valve.

Let me know if you all want to know or see anything specific. I'll take some pictures soon.

I did run into some issues with some bad gas that would make cold starts super difficult and almost fouling spark plugs. A few gallons of new gas and it was good to go. I ran it and drove it down the road today. It rips and sounds great. But... on the return trip the check engine light came on... code was p0500 vehicle speed sensor malfunction. I assumed that the manual trans T100 did not have a vss. Turns out the cable driven speedometer has a sort of 4 pulse vss in it. All the aftermarket spedometer sensor generators I could find were 8 and 16. So I tore apart the gauge and speedometer and found the sensor. It's one wire to ground and one to the ECU. The downside is I have to choose between no CEL or no spedometer to make it work and pass inspection. If anyone has any suggestions to make both work let me know.

Never seen an issue caused by the dash vss.  Worked fine from our 85sr5 dash to t100 3rz ecu.

What year t100 ecu are you using?

Worked on the VSS deal today. I found that the 1st gen gauge cluster actually has it's own VSS built into the cable drive just like the T100. There are just 2 tabs right above where the cable connects to the speedometer. One wire goes to ground the other gets soldered to the VSS wire on the harness and it works perfect! According to the OBD reader and a test drive around the neighborhood it seems to be working correctly with no CEL.

We used a 95 t100 2wd.
Glad you got it squared away.

Exhaust

  For the exhaust, I tried to reuse as much of the factory Toyota bits to try and keep the overall length of everything the same as it was in the T100.
   The first section after the collector has the bung for the O2 sensor. When you rout the crossover to the driver side, it points the front O2 sensor straight into the frame. I just cut the before and after the bumg, then welded it in a more optimal position for the sensor and flange to the cat.
   For the cat I had to cut the tail section to get the exhaust to route around the middle u shaped crossmember. Simple cut and weld.
   Finished it off with a Magnaflow muffler and DIY piping from the parts store.

One problem I ran into was the engine was a son of a pregnant dog to start when it was cold and my brand new spark plugs were almost fouled. Turns out my gas went bad since I'm taking so long lol. 10 gallons of Shell 91 and it starts super easy


Miscellaneous wire routing and charcoal canister. placement....

Radiator

   The way mine turned out was kind of a pain. The 3.0 Ebay radiator I got did not bolt in very well. I had to use spacers so the lower part of the radiator wouldn't hit the front frame crossmember. Using the spacers in turn made real estate for a cooling fan very tight. I ended up with just under 3 inches from the water pump pulley to the radiator. In hindsight, I should have cut out the crossmember and welded a new one in a little further forward.
   I used a 14inch puller fan from Amazon. Bolted in some flat bar to mount it and hopefully it will be enough. The water temp just driving the truck around with no fan never gets above 190ish but, we will see what happens this summer heading up 50 to the Rubicon.
   I mounted up a temp gauge in the ashtray slot on the dash and I will be running the fan off just a simple on/off switch and relay.

It does close. I had to cut a small section if the support to clear the radiator cap.

My goal is by the end of the month. Ive got the power steering lines and front shocks to finish. Then I have to get the truck's ecu verified by the toyota dealer. Only problem is I've been move to day shift at work Mon-Fri and it's a son of a pregnant dog to get days off. Hopefully the refs are open Saturdays.
