I have ordered the 4 pin wiring harness, but it is backordered and I need to pull my M416 trailer this weekend... Does anyone have the wiring diagram so that I can pigtail into the wiring to get me through this camping trip. I know, I know, its much better to use the wiring harness because it is plug and play, but I can't get it until late this month and leave for the trip tomorrow. Any help??
