RA062824

I was working on my camera switch one which I had installed, (I can switch between truck reversing, truck front view, truck tub/hitch view, van rear view and van overhead view) and suddenly the dash lights all went out. The truck still starts and runs OK but no dash lights, no readouts, etc. I was rewiring the trailer plug from a 7 pin round to a 12 pin flat to accommodate extra cameras . When testing the vehicle lights, everything was haywire. The right indicator was flashing the right indicator on the truck but the right tail lights on the van. The left indicator was blinking rapidly, even when the van was unplugged. I have rechecked the plug wiring and connections and everything seem correct.

I'm sure something blew somewhere but with the bundle of wires I have now and the lousy wiring diagrams I have access to I can't find either a short or a fuse and am really flying blind about this.

Any help or a direction to look would be most helpful.
