I have a 1978 blazer the dash lights work but not the gauges none of them. it does have power at the fuse in the fuse panel and wires leading up to the cluster are all in good condition. the last owner switched it from a auto to a 4spd could it have something to do with that? mabe ignition not telling it im turning the key ?? im very lost any help would be nice thank you in advance.

also im not good with wiring at all

 

yeah i hate electrical anything myself. years ago had a similar issue in a 85. ended up being for whatever reason there was no power going to the gauges even though the fuse was good. so i just ran my own power wire from the fuse box up to the gauges and that fixed it. no idea what wire it was this was a while ago.
