I have a '92 Explorer and an '87 Bronco 2. Right now the 2.9L in the Bronco 2 is running fine. I am, however, getting my facts together for the 4.0L swap so that when the 2.9L does let go (we know eventually it will) I can be ready.
Specifically, where will I run into problems with wiring, going from a '92 to an '87? I'd like to keep my stock '87 dash. Tach, idiot oil pressure light, and all. I'm all about originality, but it could use some more power. I'd like it to function like stock, with all the gauges and lights working as they did from the factory. Without lifting the hood or stepping hard on the gas, I don't want to be able to tell that the motor has been changed. Is this possible?
I don't want any goofiness where I have to explain to people that "Oh, this or that doesn't work because I changed the engine and it wont wire up correctly."
I'm not afraid of splicing wires or building my own harness with adapter plugs if I have to, but I'd like to know if the electrical signals themselves will be correct.
