The black wire is normally the ground, if it was fused, the
orange wire is probably the hot wire. I have no Idea what the red wire is, but
try the orange and black wire, and see what you get.

Subject: VHF Radio Hookup
I have an old Unimetrics Sea Hawk
50 VHF radio that I want to install. The previous owner gave it to me without
a manual or any explanation. It seems to work OK but I have a question that I
hope one of you can answer. The wiring harness has a red and black wire,
naturally, but also an orange wire with an in-line fuse. The red and black
wires were cut so I don’t know if the red wire was fused or not. Any ideas on
the proper power hookup for the red and orange wires?
