Temperature gauge
I have a 1981, and I have replaced everything on the top end,everything Edelbrock including E street heads,well after doing all that cranked it up,also has long tube headers,dual exhaust,decided to have a shop to replace cam,and all new bearings and oil pump,new harmonic balancer,new fuel pump,well,Now,my gauges aren’t working,I know my fuel gauge was working,and battery charging,but now nothing,temp gauge not working either,I do remember some ground wires that were hooked up,not sure if that’s my problem,and the shop didn’t hook it back up,thanks.

On most of the C3 cars there is only one wire going to the temp sensor, the base of the temperature sending unit gets it’s ground from the engine. If you don’t see the engine has any ground wires, that is your problem. Take it back to the shop, they are not very thorough with their work.

Yea,after seeing what they have done,what I visually see anyway,wrong blot In alternator adjusting guide,stripped the threads on it,had a starter bolt in the wrong hole on my AC compressor,broke the bracket on the dip stick tubing that bolts to the block,not to mention on my radiator support,not sure why,but he removed my original bolts,and just put all different color and length bolts back in it.so,not taking it back to them,but they probably have a ground wire off some where.

No,have not checked it,but the gauges were working when I took it to him,so,other than pull engine and put cam in it,and reinstall,he didn’t do anything to blow a fuse,unless he didn’t disconnect battery,which would be the very first thing you would do.but,who knows,I will track it down.

I don't know specifically what an '81 has for electricals vs. my '72, so take this as just a SWAG:
Are all the wires hooked up at the horn relay? (On a '72 a bunch of important components are connected there and run through it.)

Still waiting on two sending units. Water and Oil senders.
