So after reading on here I checked tube on front of head and I got 8 volts to valve but it dont close. I owned the truck about 5 months and it has closed before.
If I got power and tube aint clogged is it just stuck? best way to free it up?
I plan on wiring directly to a switch for exhaust brake and not connected to factory harness.
