12V Hardwire.

[Kaleb]

Hello, I'm wanting to add some blue lights above the pedals at the feet of my 2010 SE Fusion. The lights I'm looking at are 12V hardwire. Can somebody give me an idea of how to wire those up? I've heard you can go into the fuse box, but then some have said to wire it straight to the battery and I've been told to cut into the column and patch in there. Basically I want them always on when the car is on, and then I'm going to wire up a flip switch to turn them off if I want. So can somebody give me a step by step on how to do this.

 

Thanks

Get a fuse adapter that replaces a fuse and gives you a hot wire. Find a fuse that's on only when the ignition is on and wire it up.

Good advice. DO NOT hack into your steering column wiring. You have a brand new car. You could end up with warranty issues.

 

If your planned mod draws 10 amps or less, an Add-A-Circuit adapter is your best solution. Any well-stocked auto parts store should carry it. No cutting, splicing, etc. Easily removed should you want to return to stock.

That's the one. I knew some retired person would have time to look it up for you. :hysterical2:

Sweet! Thanks guys. One more question though. That adapter only has 1 lead out. Where does the other wire on the lights go? I've heard you ground it to the metal of the car?

Yes, the ground wire goes to a good metal piece under the dash (without paint).

Alright, Thanks

Hell yeah! I'm ready to go now but I've got at least 10 more years. I don't have one of those cushy gummint jobs you know........ :hysterical:

You have my full sympathy. :P

Ok, so I'm having some issues. I bought the correct Add-a-circuit and got it plugged into the lane merger warning and Back up sensor fuse, number 30 something. Nothing works. I got 10 amp fuses plugged in both slots in the add-a-circuit and neither the lights, nor the back up sensors work anymore. I really have no idea what the problem is. Can somebody give me a very clear step by step on how to use these things. I think its my ground. I tested the lights with a 9V battery and they worked, but only when I plugged the ground wire into the negative slot on the batter. So I literally taped the ground wire to the chassis under the car and still nothing. Please help.

First make sure the fuses didn't blow and that they're seated all the way. Were you doing the test with the ignition on? That circuit may only be hot when the ignition is on so if it wasn't then it won't get power. Other than that it sounds exactly like a bad ground. You have to attach the ground wire to bare metal that's in contact with the metal chassis. Get a longer wire and run it back to the negative battery terminal if necessary for testing. If that works then you know the hot wire and fuses and switch are working. Then you just need to find a suitable ground.

Thanks for your help but I went to bed, and figured it out with a fresh head this morning. I guess you can't just tape it to any spot on the chassis, I found a screw under the dash quite a ways up that had a bunch of wires attached to it. So I guess that it was a grounding screw of some sort and I used an eyelet to attach my ground wire, and my add-a-circuit in slot 35 (Back up sensors, lane merger warning, ect.) so it only comes on in ACC or ignition and it works just fine. Thanks.

I'll try to post some pictures when I finish.

I forgot to mention that electricity won't transfer through paint, so you need bare metal. The grounding screw goes through the paint into the unpainted metal.

here is the control box. A switch and project box from radio shack with everything wired inside. Since the dash lights are blue I went with a blue light up switch and blue lights. The sticks aren't stuck up yet, I'm waiting until it gets dark so I know what angle they are at. I've cleaned the wires up since this picture. They go from the box, into the groove under the center unit, one goes to the drivers lights and the other stick goes through the center unit and under the glovebox.
