    I just bought a brand new 2008+ wiring harness for both the plow side and truck side... Also got the Smartlights for my Plow.

    The wiring harness on truckside is all installed and i followed the instructions
    The plow side harness is installed besides the 2 seperate wires that go into the "box" which I am unsure where they go since it use to be a 11pin plow.

    I tested the lights turn signals work, park lights work... but no headlights either high or low also when i hit the switch to plow my truck lights are still on.
    When I hit the turn signals I get the lamp out light on my dash.
    I also tested the controller and can hear clicking coming from the manifold so I believe those are working as well(havent powered up the power unit yet since I still have to flush the system)

    So I read on another thread to check for power etc.

    I checked my incab power source at the cig lighter and it is getting 11-12v reading with the key on.
    I also checked the dual burn wire and it also is getting 13-14v reading.
    Is there anything else I should be checking?
    How do i check if the switch is bad(truck/plow switch)?
    Also the wires for the truck/plow switch does it matter which way they go?
    Also even with the plow not connected if i select plow my truck lights should go off no?

    Also just tested the switch found the wire from the harness that is giving me 11-12v with the key on pluged that into the switch then i unplugged the other end of the switch
    set it to truck mode tested the unplugged end(wire to the switch) nothing
    set it to plow more tested... got 11-12v so the switch does work... can anyone tell me where to check next down the system?
    Also does the controller have to be plugged in for the truck lights to turn off while i am set to plow mode?

    tested the bumper connector on vehicle side
    turn signals were jumping up to around 5-7volts
    park light was 12v
    nothing at the lowbeam or high beam connector
    so the problem is between the bumper connector on truck side and the headlight switch

    With the HB5 headlamps no adapters are required.

    I have an 2004 2500 and I did not have to use adapters.
