Interesting Problem...

[Chevelle Kid]

So I was moving my B2 around last night and my gauge lights, 4x4 control lights, shifter lights, parking lights and taillights just died. My fuses were fine, so I think it's the headlight switch...what do you guys think?

Check the dimmer switch, I just did a cluster swap and if you turn the lights on without the dimmer pluged in (equivalent of it going bad) the cluster will not illuminate.

Happened to me before and it was the headlight/dimmer assembly

Check you couplers in the engine compartment, also the the wire that feeds it from the starter relay if you have one. On my 88 the green wire with a loop feeds my dash power.
