    It's an on/off switch on the dash of a 2014 t660 says Haldex on the lower face. I was thinking maybe a dump valve but was never told that we have truck operated dumps. 20170909_100407.jpg

    @TripleSix may be able to help; he does heavy haul I believe. Haldex is a hydralics company.

    Haldex also does all wheel drive for cars too, according to wikipedia, maybe a power divider to the axel.

    Not yet, I'm sure they know, it just didn't pop into my head till yesterday, after i was in and out of the shop.

    I Do know everything they put on these trucks is on them for a purpose.

    If theres no wet kit/PTO setup, and no lift axle on the tractor, I would think it would be for a air dump valve for the trailer suspension.

    Also could be lift axle for a 3-8 axle trailer. Is there a second pigtail port with a single wire where the electrical pigtail plugs in at the tractor side?
