I understand they are different, and I'd like to know how they are, I have the dealership wiring schematics for the 99 wiring, and I have the Chilton for the other years, and all it says is that the 97 and 99 harnesses have 1 pin out difference as far as the pcm connection goes. (Ie coil pack) but as far as where the pcm harness connects to the engine harness and where the engine harness connects under the dash I would like to see if the pin location is different. (Trying to not have to buy another harness)
