TOYOTA WIRING...
This is one of those posts that probably won't make a lot of sense until you're staring at the wires. I don't have a lot of meaningful pictures here. Hopefully the instructions are enough. The EWD was very helpful here:
This link was very helpful but it wasn't perfect: Vortec Swap - Pin Out Sheets - https://forum.ih8mud.com/threads/vortec-swap-pin-out-sheets.944939/
Deviations from above link:
IH1 –
pin 22 removed (fuel pump rewired)
pin 8 no relay. 6L80e transmission wants to see 12v when brakes applied
Pin 23 removed
Pin 20 removed
Pins 5 & 6 left in place. The ‘branch’ or ‘split’ from pin 5 (yellow wire) was simply removed and the wire was spliced back together.
Pin 9 is used as a trigger wire for the relay labeled “Keyed Power.” (Coming later) This relay powers the bus bar and is hot in crank and run.
IH2-
Pin 11 removed
Any wires that ran to gray ECU plugs were depinned and removed.
IH3 disappears completely
Coil wires were depinned from plug over the driver's side fender
All EFI wires removed from fuse block over DS fender. This left me with one loose ground wire.
IH2: Pins 4-8 run to the console and will be connected to the shifter (we'll discuss that later)
IH1: Pin 3 runs to the console (will be used for reverse lights / dash indicator later)
Pin 14 goes to console (Park/Neutral safety switch) to close the circuit and send signal to starter solenoid to allow it to turn over. Power output from P/N switches directed to relay that closes when in either gear - we'll get to this in more detail later.
I had depinned 5&6 but had been reluctant to pull them from the square transfer case plug. These were removed and the empty slots in the plug filled with silicone.
This was also the time to open up the fuse/relay block over the DS wheel well and remove unnecessary wires as noted above.
