Ok after searching this fourm to find my problem I am more lost then what i was. My boat trailer lights do not work when they are hooked up on my taco. I redid the boat trailers wire to make sure that didnt work but of course that didnt help any.
I used my meter to see if I am getting any fire on my trailer plug. After testing all of them, none of them showed any fire coming to the back of the truck. So i traced the harness back to the tailight and checked those fuses. One of the caution light fuses was blown so I figured that might have been the problem but after replacing that fuse still nothing. There is also a black box where the wires run in and out of. Idk if this is the problem or not but I didnt want to break anything by opening it up.
Then I figured maybe the fuses up front are blown. But after checking them they seemed all right.
I have gave up on trying to fix this thing. I've bout got to the point in going a buying a whole new harness and installing it which I would rather not buy. Any tell me what they think the problem is?
