'03 K1500: Where do you tap into accessory power for the controller?

    Hi guys,

    I'm almost finished wiring my '03 K1500 for a fisher MM setup.

    I thought tapping into an accessory power was going to be a breeze BUT I realized the fuse box is under the hood and not in the cab.

    What do you guys do for tapping into accessory power?

    I could run the red wire backk through the firewall and into the fuse box, BUT I would rather keep it in the cab (if it makes sense to do that)

    Thanks,
    beatle78

    You have a relay center under the hood with relays/fuses in it, but when you open the drivers side door, on the side of the dash there is a panel you can pop off and under it is the fuse box. when wiring my boss i had to tap into a switched power and thats where i got it. hope this helps. my truck is also an 03, but a gmc.

    Those add a circuit's that b&b uses is what was on my wiring for my boss plow, and i just popped out my ignition fuse for my truck and put that in, they work awesome and seem safer then just plugging wires in.

    I always run my own fused wire Directly from the battery And run several accessories from there depending on amp draw.A plow controll has little amp draw so Add a circut is fine.

    all you hafta do is buy a "t-tap" and take your dash off, its really easy, there will be two 9/32nds bolts on the little dash part under your steering wheel, than it will pop off. take a 10 millimeter with a ratched and take that metal piece off that goes around your steering post. there will be a couple big wires under there, red, pink, posibly a bigger yellow one. take the t-tap and crimp it onto your pink wire, this is your "ignition" wire. than run that wire to your accessory power.

    I bought an add a circuit, thanks to B&B, and thanks to Onebadbowtie86, I found out there was another fuse panel on the side of the driver's side dash. I just need to pickup a grommet tomorrow to put in the 5/8" hole I drilled in the firewall for the 6 pin connector!
