Guys have done a search on here and have seen where to tie on to the coil signal wire at the pcm. But I have already ran my wire to the passenger side of the engine. So I was wondering if anyone knows what color the wire is to get the RPM signal from for my window switch.? I have noticed all the coils have a common purple wire and the other wire has a stripe. This is all that I have left to finish my install but I have not found the exact info to feel safe about hooking to the coil wire. Thanks
