Well now I don't know what to tell you, I guess you'll have to call BOSS tech help line their # is 906-776-3500. I'm looking at the manual as I've installed both Chevy & Dodge 2001 trucks 2-months ago & both had the relays & option connectors. It appears that they all have the vehicle light option plug. Brent
It sounds like we have to different versions of the harness. In last years harness we had the relay in the light adapter, specific to the vehicle. In this years harness we have the relays in the main harness. Does that help?
