Thanks... I think I'm going to give it a go... at least to get to #1... the engine running phase.
I have the 2UZ, full harness along the auto it came with all connected and an H151 5 speed with the ECU that was on the truck that ran it (connected to a 2UZ)... so I suspect I have all (more than) i need to get this running.
Just be sure that the donor vehicle didn't have an immobilizer system, because if it did, you need the correct ECU and matched immob box, plus the matching keys & transponder ring from the ignition switch.
