How interchangeable are Corolla engine wiring harnesses?

Question

I need to find a engine wiring harness to put in a 97 Geo Prizm (a clone of the 97 Corolla) that has a 1.8L 7A-FE engine.

Toyota started putting 7A-FE engines in Corollas in 1993. Is a wiring harness from a 1993 (or whatever) Corolla interchangeable with a 1997 Prizm/Corolla?

Is there somewhere on the Internet with this sort of information.

Besides the 1.8L engine size, I assume the the harness needs to come from a car with AT & AC to match the car it's going into. The car it's going into doesn't have factory cruise control; does it matter if the harness comes from a car with factory cruise control?

I think you should ask the dealer
