So I have a situation where all my "running" lights on the right side of my trailer (looking from the back) isn't working. Originally I thought it would be the connector at the car, sink replaced it with a 13 pole connector, no change. I found that there might be a computer somewhere, or does anyone else have a guess?

@Jessenjonas Is it the 'Sidelight' / Position light on the Trailer not on when Sidelights are on on the car. Or do you have them to be on with the cars front DRL,s?

Right now, only on the left side... could be some broken wiring, but the issue is that I'm not sure how this is wired, if is is original, then I was hoping there would be some great documentation about it, if it is DIY, then I would have to dig into the car, but right now: position light: only works on left side. Brake: both sites. Blinkers: both sites.

?Is it a forward facing 'Sidelight'? Or is it a rear SIDELIGHT?

Well, essentially it is everything on pin 5, so all normal lights that is normally associated with the right side

Maybe show your location / country and when posting say it is a Left Hand Drive car. I read right light and just assumed a Right hand drive car.

Ahh sorry.

Denmark, left hand drive. I guess there could be differences of course.

Well, just found out why.

Seems the wire was broken somewhere between the trunk and the slot.

So we daisy changed the wire from the left side to the right side and now it worked.

Will have to check the correct wire sometime during the summer as it looks like the fog light isn't turning on as well, which is wired.
