Yes, there is an adapter harness that converts the stock coil wiring to allow coil on plugs to function. From personal experience, when I tried the conversion, it would only start every once in a while. However, when I could get it to start, it ran like a champ. As soon as I converted back to the coil packs and wires, it started every time. I'm still unsure as to why I had so many issues, because it seems like other people run the COP swap and never run into any issues.can sn95 coils be switched to a 99-04 style? somehow get rid of all the wires running through the front?
