A current limiting resistor capable of dissipating power greater than about Watt is incorporated between the output circuitry of an aftermarket electrical system and an output terminal, so that the output circuitry is protected from excessive currents flowing through the output terminal as a consequence of incorrect connections being made to the output terminal. The resistor has a value of approximately forty Ohms, and a power dissipation rating of three Watts. When correct connections are made, the resistor will permit a current flow from the output terminal of approximately ninety milliAmps through a relay winding, which is sufficient to activate the relay. However, in the case of a miswiring, the resistor will limit the current flow through the output circuitry to no more than about 300 milliAmps
