Roe, does it have a voltage regulator on the firewall?
if not you can splice into the harness to add it.

same with the intake fuel pump, you can splice it to run with key and use regulator/return line for the carb.
it keeps the under hood harness intact and looking un molested/hacked up that way.
my self, I always get a 82-86 wire harness untape it,remove what I don't need and retape it. not that hard to swap out the complete wire harness underhood /indash.
just taped my 86 harness back up for the 82w350 next.
