Had problems eversince I owned my 4track Independant with the wiring for towing my trailer. Have spent ages trying to figure out why it wouldn't work properly and eventually managed to get it so it all seemed to do things in the right order, ie brake lights come on when brake pedal pressed etc. Anyway I just bought a new trailer and it didn't work when I plugged it in so have spent ages fiddlng about with the wires behind the n/s rear lamp cluster. So it's kinda working now but not quite right.
My current problems/questions are, In amongst the wires there are a couple or relays. There are two together with what looks like 4 wires going into each. At the moment when i have the lights on and press the brake, the tail lights and brake lights stay on till i switch lights off. If I disconnect either of these relays that problem stops. (are they important?) Other thing thats started is when I press the brake there's another relay thats started buzzing while pedal is pressed. All this only happens when trailer is plugged in. It's not the trailer as it's been tried on other vehicles and it is brand new. It's not the indicator relay buzzing either it's a different relay but I don't know what it's for.
Anyway does anybody have any ideas or should I just keep fiddling with the wires?
