Hey all,

So I'm putting my diode dynamics footwell leds into my 2009 ford f150. Just to be safe I want to double check which wire color is which on the 12V accessory (not the cig lighter). I don't want to tap into the wires backwards.

Which 12v accessory? Can I suggest buying an "add a fuse" and getting your power from the fuse panel in the passenger kick plate

I would be open to buying an add a fuse. The only thing is, I do not know how to use those exactly. I know there is only one wire coming off of the fuse, and there are two wires (+ and negative/ground) used for the wiring of the led controller box. I think the kit was specifically designed for splicing. But, like I said, this is not my area of expertise. I just don't want to pay over $300 for ford to do it...

Sorry, forgot about the other part of your question. It is the 12V next to the airbag on the passenger side of the dashboard.

the add a fuse is your power wire only, you can ground your light directly to the chassis if you want.

Add a fuse is a simple little thing, 1 wire coming off it is your positive, you remove a fuse from your fuse box, insert the add a fuse, in the now vacant fuse spot, replace the fuse on the add a fuse (now have 2 fuses on the add a fuse) the positive wire from your light goes to the add a fuse wire, the negative will go to a chassis screw/bolt basically any screw bolted to metal should work.

If you want to use the 12v accessory the middle pin in the positive, the outer pins are negative.
Be sure to add a switch because the 12v receptacle is always on

Add-a-fuse is a convenient way to quickly access 12v power, however only if you're willing to alter the OEM molded plastic fuse box and/or run without the fuse box lid installed. I wasn't willing to do either, so used Posi-Taps off existing wiring. For those unaware, Posi-Taps (available in small quantities from this seller) are minimally invasive to host wiring, i.e., leave only a small pin ***** in wiring insulation if or when removed.

You can jump on YouTube there's a few videos on there I've seen

Thanks for all your thoughts guys! I think I'm going to stay with the splices. Electrical tape is an easier fix than having to buy a new fuse cover if I ever have to take the lights out. I gotta wait until I get my truck back from the shop...the steering was sticking . I'll post pictures of the job after it's done in a different thread.
