Yes, you can use the key on power wire to run another relay and that
will likely take care of things for now. It only masks the problem so
the problem may worsen and come back to bite you later. I would at least
check the connection inside the wiring box on the firewall. The black
wire from the key should have a splice in there that you can find. Find
it and use the hat pin trick to see if that is where your problem in.
The hat pin is used to poke through the wire insulation to inner metal
wire on each side of the connector to check if the voltage is the same
on both sides. It is isn't then the connection is the problem.
