Also, the power steering pump decided to poop the bed. I test drove it for about 5 miles and when I got home the reservoir was overflowing and bubbling while it was running. Let it sit over night and now the brand new fluid is kinda foggy red with little metal flakes in it.

I finally got a call back from the Alemeda college referee today. According to him I am good to go. He said the engine family located in the door jamb of the donor truck had to be VCK11LCRMDK and under the hood TTY3.42JG1GK. It does not matter if the ECU is for a 2wd, just as long as it is for a manual transmission. As for the ECU check I would be good to go to get a printout from the Toyota parts department showing it is the matching ECU for the donor truck VIN. According to him these ECUs aren't really programmable and the will be checking that during the inspection. suggested to do what I guess is a smog pre-test to check all the emissions monitors since I dont have the capability myself. However, he said my intake would be up to the shop supervisor's discretion if not having the heat shield on the intake is acceptable or not.  Lastly, the exhaust crossover is still allowed. Fingers crossed I'm going to send it and hope for the best.

I almost forgot about making sure all the emissions monitors are working before setting up my inspection. I've driven the truck about 105miles the last few days and all but the catalyst monitor seems to be working. I understand there is a specific drive cycle that should set everything but I dont really have the place to do it exactly as the instructions say. Does anyone have any tips to get it to read ok?

Normally you can get the catalyst to kick by running down the freeeay for a bit. Itll take two trips.

Today I went ahead and took the truck to the referee. It did not pass. I'm not really surprised but I have a better idea of what needs to be done. Of course the cat monitor was not ready but I also did not have the brake light switch wired to the ECU. So even if the cat monitor was set I would have failed anyway because I didn't know the ECU needed a signal from the brake switch. Go thing is that just those 2 items were the only thing that failed me. The refs said that a couple things could be wrong considering I've driven the truck a couple hundred miles already.
1. The cat could be old and losing efficiency since it is the OEM cat with 160k miles on it.
2. The truck is running borderline too cold on the highway. It usually runs about 185-188* when it below 90* outside. It has the OEM 180* thermostat so I may try putting in a 192* thermostat and see what happens.
3. The ECU might be losing power when the key is off so it resets some of the monitors every time I shut it off.

They also told me I got lucky. There are 2 versions of the 5vz. One with the EGR and one without. The documents they had weren't clear on how to tell which one is which so they looked up the past smog test history from the VIN on the donor truck.

Other note, the truck tends to very slowly over heat while it's not moving and given any throttle even with the cooling fan on. It boiled over once when they forgot to turn the fan on despite me telling them about it and the instructions I taped to the steering wheel. I'm not sure if I need to do something like get a 2nd fan or a bigger fan. Also I dont know what the were checking but it was getting up to about 230* when they were revving it to 2500rpm. They even had a 2nd larger fan blowing at it from the grill.

My referee knows all about the different ecus. I had to go out and buy a different one and find all the egr components to make it legal. He said he goes by weight class and the t100 I have is a heavy duty t100. So that's the reason why I needed a different ECU and egr. Bunch of BS.... Still haven't started on the swap. I want to install all the new parts on the t100 first to make sure I don't have issues later when it's in my truck. Good luck with your swap.

Quick update.

After 3 weeks fighting with one supplier and ordering from another, I got a new catalytic converter. Got it bolted/cut/welded in today. First drive out and the cat monitor is now set. I'm 90% I got the brake switch input wired to the ECU. I want to have someone with a scan tool verify it is working correctly before I schedule my next inspection. Also got the 190* thermostat in and a new 16" 2500cfm Flex a Lite fan hooked up and it is maintaining the coolant temps much better.

Anyone happen to know another way to check the brake switch input is working correctly? I might be paranoid but I wired it using a wiring diagram from a Haynes manual and I just dont quite trust it.

Just check to see if signal changes with brake input. Simple as that.
