Abstract
Abstract To match the wires of a pickup to a trailer, a conversion box is provided. The jumper adapters are used to convert the plugs from the pickup to a six connection plug. Another adapter connects the wires from the trailer to a six wire connector. Therefore, a standard six wire box is used regardless of the fact that the pickup and the trailer may neither have six wires nor the same number of wires as the other. The wires from the pickup are connected to switch wires which have banana plugs on the end. The wires from the trailer are connected to receptacles so that when each switch wire is plugged into a receptacle, a connection is made. Lights on the box are used to indicate which of the truck wires are activated.
