I'm new to this forum so ill start by saying hi lol. I've recently installed a starter button onto my E36 328 with toggle switch for the ignition, EWS bypass and a seperate toad alarm/immobiliser system and on I stalling my button I have come across two wires that I'm not sure off I have the red power cable the purple aux cable the green ignition cable an the yellow and black starter cable all wired up and it seems to be working fine although I think I have a dodgy starter (next job) the two wires I'm not sure of are also in the same loom to the old ign switch and they are small wires ones red and green and one is gray and green, can anybody shed some light on these. Many thanks guys.
