Mobieus_uk Posted May 15, 2017 Report Share Posted May 15, 2017 the duel colour are most likely speakers, to work out what goes where stick you multimeter onto ohms connect one wire to the multmeter and then just touch the other wire, one of the speakers should crackle thick red is most likely the permanent live, you just need to work out which of the other wires goes live with the igntion on, which will leave the last wire as ground its pretty easy with multimeter Quote Link to comment Share on other sites More sharing options...
