Hi All
I need some help with wiring up my lights for my boat trailer.



The lights I have installed on my running board have 5 wires which are detailed as follows:
Black – Earth
Yellow – Indicator
Red – Stop/Brake
White – Reverse
Green – Tail/Running


Obviously I have one on either side of the running board and need to wire these to a 7 pin Pollak plug to connect to my 2012 XLT.
I have the wiring diagram that came with the truck however I cannot figure out the brakes/indicator wiring for the plug. On the diagram it has pin 5 and 6 as the left/right indicators and brake lights however if I connect the indicator and brake lights as mentioned in the diagram, then as soon as I apply brakes or use the indicators both lights come on at the same time.


I’ve also tried keeping the indicators on pins 5 and 6 and connect the brake lights to pin 2, brake controller output, instead as I have no brakes on my trailer however when I apply brakes then the indicator lights come on. I have double checked the cabling and the connections are correct and all the other lights work fine except the brake lights.



I’m no auto electrician so apologies if I have missed something obvious but I would appreciate any help regarding this
