I need someone to tell me where the 3 harness plugs on the wiring harness plug into the fuse box. @ under the hood. I have all the OEM wiring harness @ lights. I think the bigger plug plugs into the trailer brake wiring spot in the fuse box. Not sure where the two smaller plugs go,@ where the harness from the back side of lights plug into under the hood.
