Dash Light problems

[Trent_McAllister]

I spent a while going through other threads but I'm not finding anything to help me.

The issue is I have no dash lights other than the high beam indicator light. I had them when I put the truck back together, but when I had the lights on for 5 minutes I smelled electrical smell and next time I started, the lights didn't come on and haven't since.

I did a few things that could of caused it when putting truck back together. It might be the original switch I reused. It might be that I replaced the T5 bulbs in the dash with LEDs and it didn't create enough resistance so it burned up wire?

Truck was apart for 2 years in a dirty shop and painter painted over the fuse block labels.
All fuses check good.
all other lights including tail lights work fine.

Can someone tell me what color(s) wire do I need to check the circuit on the back of dash plug or if it is possible it's just a bad switch?
