The instructions on the site were really helpful as i remember, I installed a raptor shift light in my stang about a year ago, although it wasn't a dual mode it was just a normal raptor shift light. I wired it to one of the wires going into one of the coil packs one to ground and one to a wire coming out of the pcm if i remember correctly. What exactly is the problem does it at least light up and do the startup check?
