i have recently fitted a avantgaurd4 to my 1986 mk2 golf, i have everything working exept my central locking, my locking is an aftermarket kit consists of 5 wires and a pcb box, when i push my lock down i get a 12v pulse on either blue or red wire which then switches a positive live which is constant (either purple or brown depending if locked or unlocked) so is this reverse polarity??? if so my clifford doesnt hold a constant live does it?? sorry for the long thread please help!!!!!!!!!!!!!!!
