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.![]()
Any help in identifying what this is

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

Do you have a wet kit on the truck? PTO switch?

I Do know everything they put on these trucks is on them for a purpose.Big Don Thanks this. -
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.
DDlighttruck, Logan76 and Gunner75 Thank this. -
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?
