This is a great replacement for the 4 way flat connector since it provides a secure connection between the receptacle lid and plug tab. Be careful with the 4 way connector, there is a version considered heavy duty with a 35 amp rating that feature a larger ground pin.

This type of connector allows for the basic connection of the three lighting functions which include running, turn, and brake lights. It also comes with one pin for ground wiring.
