Re: auto wiring
that old you will probably have to splice. get the little blue connectors, that slip over the wires on the car, and you slip the trailer pig tail wire into an squeese with pliers. make the job really easy. remember most trailer light problems ar caused by a bad ground. don't depend on the hitch and ball to do the grounding. the white wire is for grounding. walmart sell the kits, including the connectors.
