That’s the reverse lamp relay. There are two yellow with red stripe wires and the purple wire you mentioned. Either the two yellow wires go to the same source and wouldn’t matter which one I use, or I’m at the wrong place. I looked on the ecu and can’t find the green with orange stripe at pin 102. It’s a bluish wire instead. Wish you had instant messenger so I could talk and get it figured out. I know it’s not as complicated as it seems, but my wires aren’t matching up to your suggestions. sorry
