There is no need to be rude. This is a 2004 vehicle it is 2008, engine combinations have changed in 4 years and so has technology, wiring diagrams, and even harness routing. Are you new to the automotive business. And I think the salesman would flip out if started pulling out a dvom and pulling on wires. The 4 cyl is all GM including the alternator and the honda engine is all honda including the alternator I thought I made that clear.
