air switch

i got my dual 400 kit yesterday, in the manual it says to wire it one way and on the hornblasters website it shows to wire it as a positive. not sure of the correct way to hook it up! any help would be great! thanks jason

Are you talking about the Pressure switch or the valve?

The valve does not matter, ground one, the other goes to your button.

THe pressure switch is marked so that should be pretty easy.

i was talking about the pressure switch, the different diagrams show a couple different ways to wire them

Which pressure switch? Which diagrams?

the switch came with the dual 400 kit that diagram that came with the kit was different from hornblasters website

The Viair & HB diagrams I found are exactly the same:

Positive “key on” ignition source —> pressure switch —> Each relay pin 86
