I am in the middle of relocating my coil packs and i have everything marked with which cylinder/spark plus it was connected to just to cover my ***. I was going to use my stock harness but its brittle and pretty worn. I can replace some wires but that seems to be a hassel. I found this set on ebay that looks pretty good and already made out for you. Here comes the question, does it matter which connector is plugged into on the coil packs? I have the old one labeled so if I got new harness would i need to bother trying to figure that out?

 

The order matters, that's what determines your firing order. The main gray connector can only plug in one way, and I would have to assume they would mark each individual plug so you can't screw it up...
