For larger length light bars (40" and 50"), it is recommended to retain the majority of this wiring harness including the relay, and switching the relay on/off with your aftermarket switch system. This is due to the majority of switch systems having a maximum amperage rating of 30A, and our larger length light bars exceeding this total rating.
