    Got a couple inches here and there but nothing realy. pulled the plow out this weekend and started to get everything ready. The good news is everythings working well with the truck and plow. I'm looking to add a back rack to mount my strobe on and was just wondering if anyone could give me some advice on running the wire through the rear firewall.

    run the wiring under the frame and to the front fire wall and bring it through where the plow wiring comes through.

    Nice! Are those 285's? I have always run my wires into the engine bay, then run them to the lights.

    yes those are the 285s, what are you guys using as a power sorce for the lights?, are you going straight to the battery or tapping into a fuse?

    I would run off the battery and install an inline fuse as close to the battery as possible.

    I agree with what the above posted. If you came through the rear you would risk letting water leak in by it following the wire. When you have a low spot it gives the water a chance to drip off to the ground and not into your truck.

    if you have the plow prep, you should have a switch on the dash. if you trace it back(or listen for the click whnet he button is pressed) there should be a relay behind the drivers seat,near the rear speakers. I ran my back rack lights down betweeen the cab and bed and right under the cab on the corner is a grommet. i snaked the wire through there to the relay.

    x2 on the grommet in the rear cab corner. thats where i run my wires. you can then follow the plastic trim along the bottom of the doors and run the wires right through there, and up into the fuse panel. easiest way in my opinion.

    yes I do have plow prep. Is the gromet located underneath the truck in the driver side cab corner? will i be able to get to it if i have an underseat storage box?
