So the Pop-up I have was modified by the previous owner to utilize a 4 pin wiring harness.
This suits me fine, since my TV only has a 4 pin receptacle.
Of course, I think he dinked it up. I need someone with a little more experience to check my logic.
Here's the existing wiring harness (with all the protection stripped away)
You can see he went Color to Color. (I bet it seemed like a good idea)
Of course, when I did my safety check, The left turn signal was weird. If the headlights were on, the break light was on, and I did not have a turn signal. If i did not have the headlights on, the turn signal operated, but seemed dim. Other lights appeared to operate normally. I assumed (I think correctly) that the wiring harness had been "modified".
Here's the manual from my camper:
So check me on this:
The correct wiring should be:
White - White
Green - Green
Brown - Brown
Red - Yellow
I'd LOVE to try tying the Black to the Green (So I get power to the Camper when the headlights are on) but I cannot guarantee the gauge of the wire in the TV, but it looks smaller than the 14 gauge in the manual. So I think I'll pass on that particular fire waiting to happen. If I really want it, I'll replace the 4 pin with a 6 Pin on the TV.
