Abstract: In some preferred embodiments, a smart socket adapter is utilized. The male plug on the towed end of the wiring harness is unplugged from the female tow port that is part of the towed vehicles wiring package. A smart socket adapter is inserted into the towed unit's female tow port and the wiring harness male plug is then plugged into the new adapter. Preferred embodiments of this adapter have smart circuits that transmit wireless signals to a verification device that is located in the towing unit. Advantages of the present invention include facilitation of a safer tow operation, because the towing operator will know at all times if the integrity of the tow connections and replication of signals has been maintained. In another embodiment, a wireless transmitting smart plug is plugged onto a standard wiring socket on the towing unit and a wireless receiving smart plug is plugged into a standard wiring socket on the towed unit.
