No Running lights, or dash lights?

[oughtsix]

Two nights ago, I noticed my dash lights start to flicker and within a few minutes, they were gone. So i get home and notice that someone had put a 25 amp fuse in for the instrument cluster. no biggie, i pop a 10 in there. Nothing. So I then decide to replace the headlamp switch, as I noticed a little portion on the switch harness that looked like it had gotten too hot. Nothing still.

So what should I check next? I just put a trialer hookup on it, but I took it off when all this started happening. Help please, until I fix this, I'm leary of driving at night. I figure I'll meet the cop having a bad day that'll give me 4 tickets for 4 markers out. Ha.
Thanks

Did you splice into the factory harness to put in the trailer hookup? If so check everything back there. I ran into a similar problem last summer, and it was the main switch, but you've already changed that. Sounds like you may need to examine the wiring.
