Im installing a diamond S hood and I got a used plug from a M6 and the plug fits but I think the wiring is different what Im looking for is can someone tell me which wires are for the lighting coil +- for 2 lights as im hooking up my egt as well and I already have a A/F hooked to the acc. plug by the steering post?And has anyone run without a tach hooked up ie no hood?any info would be great
