Hi all, have a 93 GQ wagon ST TB42 EFI manual, previous owner had to change the wiring loom, he has bought an AUTO SAFARI LOOM, as it has fuse and wiring under seats for HEATED SEATS & AUTO COMPUTER, I bought it with loom half fitted with nothing hooked up, got almost everything sorted and working so far, even all electric windows work, problem I am having is can't get reverse lights to work. Have found the reverse light wires in auto plugs up near main loom(none of them actually plug into anything) have also worked out wire for reverse light switch on manual box, but they goto a relay near battery that is marked PTC HEATER, now when I select reverse that relay starts buzzing. I thought I could just bypass relay but don't know what it actually controls, so don't want to fry wiring or stuff anything, so any help would be appreciated.
