Messed with trailer wiring, now most lights don't turn on...

I have an 00 F450 with a 350 bed in it. I was going to tow a trailer and had the wrong plug for it in the middle of no where so I just took my 4 pin trailer plug which was very old already and cut the 4 wires going to it and just attached them to the trailers connector and taped them on temporarily for the trip. I was done and returned the trailer and was busy with work and school to tape the ends of the wires so the 4 trailer wires on my truck were exposed for the rain all day.

Ever since, when I turn the light knob on the dash to the first position to turn on all the lights but the headlamps or headlight setting no rear/side-fender marker lights/cab lights/front markers lights work and also my gauges on the dash don't illuminate, but the warning lights, wts light and high beam light indicators work.

But headlights work, signals front and rear, brake lights, and hazards all work if I use them. I checked all the fuses interior and under hood and they all check out. I figured from the rain and driving the wires must of touched and shorted out a fuse but they are all good from what I can see. I specifically checked all the lighting and trailer fuses and they are good.


Kind of confused.

I know you said you checked the fuses, but did you replace them? Fuses have been known to do weird things.

Just a suggestion

I was beginning to think that. Will be back with an update.

Ended up being a fuse that looked fine but was really out.

Glad you found it!!!!
