The motor is from a 1990 4-Runner, I believe that the harness is the same from truck to 4-runner.
The only thing I know of that is different is the 4-runner had rear seat heat, and on the motor is a aux. pump and the w.p. has an extra line from it as well. I have a spare motor from a truck that has the pieces to remove this if needed.
No Headers on it. I have a Nissan 300ZX turbo charger that I was going to put on it, so you need the stock manifolds to do that with.
