:help: Hey diesel nuts! I'm a newbie, just got my 2005 Sierra 4WD x reg cab a few months ago. I bought some after market Onki Floorboards and they come with lighting. Has anyone wired these babies up? I am very ignorant about the wiring, just installing them about killed me! No drill kit my Censored . Please post if you know how to wire these things, they came with no instructions, just wires. Love this truck, put her on cruise in the foothills of the Smokies towing a loaded 7 x 14 cargo trailor full of furniture and the Duramax doesn't know it's back there and the Allison doesn't even down shift on pretty steep grades. This is the truck I've been looking for all my life! My first diesel.

Do a search in the DIY section for Cab lights install. The instrucions cover installing and wiring the roof marker lights, but I bet you could wire your floorboards to the same location. Or you could tie them into the brown wire of your trailer harness.
