Electrical problems on my Ram

[Kgin Ram]

I need Help!!!

I have a "96 Ram 2500 4x4 Diesel and am having an electrical problem. Maybe someone out there can help me.
My running lights, gauges and speedometer/ odometer quit working. Checked all fuses and relays. All check out fine. Headlights, brake lights and turn signals work fine.
Can anybody help???

Check the connections on the main fuse block under the hood. sounds like the problem could be there. If not, I would almost suspect the headlight switch, they have been known to fail from time to time.
