Electrical Question
I just obtained an early 81 Corvette with a new crate motor. It runs great but some of the electrical system isn't working. The door locks, radio, dome light and horn don't work. All the fuses appear good. I was wondering if during the engine replacement, something got unplugged. I'm getting ready to upgrade the seats and upholstery and would like to get the electrical problem fixed while the interior is out. Any suggestions on where to start looking are appreciated

Hi and welcome!
Dome light:
You might have a delay relay (small orange box behind the lower passengers dash) that went bad and is disconnected. You can get a new relay but first remove the relay and connect the two white wires together and the lights should go on and off as you open and close the doors.
Horn how to by Willcox:
Radio:
Check the usual suspects, power and ground at the radio connector.
New radios have a built in fuse, is yours original or newer?
