I have a 91 4runner with seized v6 engine and a 91 truck with a strong running 22RE. I'm a little low on cash and want to suffer the horsepower loss by swaping the 4cyl out of the truck into the 4runner.
My question is mainly concerning the computer, I want all the power features (power windows and power locks) in the 4runner to work properly while running a 22RE. Do I need a different ECU to make this swap happen?

The ECU controls the EFI, Emissions, and Auto Trans (if so equipped), and the 4 cyl and 6 cyl are different, so you'll have to swap ECU and harness.

The power windows and locks have their own ECUs (relays) and wiring.

When swapping ECU's the part number must match exactly.
