This won't work... remember - there are 2 injectors in a 4.3, the 2.5 has only one. That is just a start. The management system is similar in both cases, but the wiring is way different.

Answer,
no,
you can't mix wiring harnesses/ECUs unless you have a degree in computer science and electrical engineering... :p

Oh, and welcome.
