Good item to mention.
Yup. Thats one of those functions they dont change the guts of often. They use the same stalks across many years of many models as well.

Something I ran into when doing my swap. I used a 2002 4x4 Tundra ECM, engine, and harness. I repurposed the front diff wiring (ADD actuator and limit switches) to supply signal to the EVAP system MAP sensor, and canister control valve, since those wires on Tundra come in from the driver's side in a separate harness. This was appealing to me to keep EVAP so that I could do away with the poorly performing 80 series one I had. Also used a couple of the wires in that same area to supply my power to the EFI main circuit which terminates on the driver's side fender in a stock 80. And instead of running a whole single wire to use the EFI main relay power, I used that instead. I will have a 2uz build to link to soon. It is currently swapped, on the road and driving, just haven't taken the time to write it up yet. Oh, and I used the original 80 series trans.

Little details that help make things polished: use an LED light bulb in place of the incandescent that came in the dash of your pre-'90s truck. Before the 90s, 5W bulbs were common and the ECU can't push that much power through its indicator circuits.
Get LED variants of whatever you need to use and your end result will work and look correct.

For you guys that have used earlier 2uz in 80s, what throttle cables have you used?

Mind posting a pic? I tried one from a 99 and it's several inches too short.

Solved it. 100 cable works well.
Was gonna say you would have to be in a significantly diffent location in the engine bay to short by a couple inches in my experience at least .

And this is why you can't use the FZ fan in your swap:
I have a 100 series for mine but I am looking. Into the maybe going with one out of a tundra/sequoia though I don’t remember why I was looking into that route

4runner or LS400/430. The truck fans get into the steering box and brake lines.
I had no clearance issue with my Tundra fan. I switched to an early 100 series fan just because the Tundra fan I had was bad. But there are no clearance issues with mine. I had thought about going the electric LS fan/shroud route, but decided to use mechanical based on other's experience with insufficient/undesired results with the electric setup. Also, the FZ fan doesn't bolt up to the UZ fan bracket anyways. I also used the Tundra throttle cable, and modified the throttle body to accept the transmission throttle cable.

The FZ clutch doesn't bolt up, but the FZ fan bolts to the UZ clutch. Thus the watch out being mentioned.
Thanks for the clarification! I did not even try unbolting it from the actual clutch. Great to know.
