73 duster horn relay ?

I can't see enough from your photos. If you can see/ access/ reach/ extend the wire, and you can solder, "yes" no reason you cannot repair it
Thanks for the reply, the problem I have is that there was no broken wire inside the relay casing to give me an idea of what this empty black wire terminal is suppose to connect to within the casing. Trying to figure out if I solder a new wire to this terminal, where does the other end connect to within the relay casing.Hope that makes sense. Thanks again.
