B2650HSDC unused connectors behind dash

[Orange1forme]

I was adding rear work lights to my new tractor and noticed a cluster of four unused connectors just below the front wiper motor.

I presume there are associated wire harnesses that would connect to them and go to their respective items. Anyone know what those might be?

Maybe a beacon light? Which would have a switch in one of the plugged holes by the hazard light switch.

I breezed through an online shop manual, but did not see anything .

Thanks

My guess is the same wiring harness may also be used on the b3350hsdc unit which utilizes the Dpf/regen sys. I have to get a set of those rear work lights ordered for my cab.

I am not using OEM lights, too expensive for the product.
