Did your truck come with factory trailer wiring - a 7 pin plug? If so check all your fuses, should be a fuse box under the hood with fuses set aside strictly for the trailer wiring. If not you will need a light adapter as stated above.
Thanks guys. I just read my initial post and found it severely lacking (it was typed on a phone after a couple hours with the lights and a few beers:sleeping
, so let me try to clarify things a bit. The truck does have the round seven pin plug under the bumper. When I first bought it I picked up an adapter so I could plug in the flat blade connectors on my trailers. I'm beginning to question myself at this point, but I seem to remember the trailer lights working correctly for a while (definitely would not swear to it). Two tows ago I had right turn/right brake only on the raft trailer (haven't towed the jon boat in a while), then the next tow I had nothing. I replaced the lights (needed to anyway) and now I have left turn/left brake only.
I figured I'd need a converter so I picked up a kit when I bought the lights. Seemed like a pretty easy process so I jumped right into it. Using a probe I was able to isolate left turn (red), right turn (brown) and brake (also brown). However, I probed every wire repeatedly and never could isolate tail. So the questions are:
Since brake and turn (at least brake and right turn and I assume brake and left turn) are on the same circuit do I need the converter? Based on the description in the link it sounds like I don't, but who knows?
Why no tail? I tried to check fuses but the diagram in the owner's manual didn't match what I saw under the hood so I didn't try very hard LOL. I'll work on that.
Why only right side before and only left side now?
So many questions!
