I'm going to be installing my DMH cutouts this weekend and I need to know the specific power source to tie into.

I dont have a clue about electrical wiring, so if you could be very specific as to the color and location of the wire I need to tap into...Thanks!!

I am not exactly sure the requirements of the cut outs or the position of your switch, but I have used the Power Outlet on the console before by removing the shift boot and splicing into the wires behind it. This will give you power with or without the ket in. As far as colors, I do not remember but there are only two wires and the positive is probably red and the negative black/brown. Post back if they are different and I can tell you. If you need to hook up the wires in the engine bay, just hook them up to the positive hook up located in the red plastic box on the passenger side fender. Just bolt it to the stud and make sure to run a ground wire for the negative.

 

Those wires are both orange. The ground has a black stripe down the side of it. I would splice into the fuse box. There are 3 places where you can crimp on a spade terminal and just plug it in to the fuse box. You will have to figure out which one you need. One if for only when the key is turned on, and the other is all of the time hot. Ground it to your console bolt or the one that holds the airbag thingy on.

 

If it was my car, I would run a simple, independant circuit directly too and from the battery.

10g red wire from positive terminal to the positive side of both cutout drives (I'm wiring them in parallel.), black 10g wire back to the negative side of the battery. The only detour would be a sort trip up to your console, on the negative (black wire) side of the circuit, following the same basic path that your linkage does and using whatever sort of switch is appropriate for your needs.

The reason I like dedicated circuits in general is twofold:
One, it avoids hacking into the factory harness at all.
Two, related to one; is that it avoids overloading a factory circuit.

The additional reason in this case is that if you end up having an unexpected conversation with Johnny Law, while your car isn't running; you can close the cutouts without even needing to put your key in the ignition.

Yes, that's sort of paranoid thinking, but just because I'm paranoid; doesn't mean they're not out to get me.

 

that sounds like a tone of extra work, 99% of the time it will come out looking alot more hacked then getting the power from a factory source.

we arnt talking about a huge amp or something, we are talking about 2 cutouts, i dont see any draw at all from mine.

even if it did draw alot of power, there is no reason at all to run a ground back to the battery. just drill a damn hole right next to the cutouts and run a sheet metal screw into it for the love of god.

 

Our unibody cars are known to sometmes have grounding problems. The two motors that drive the cutouts would likely pull a few amps if wired in parallel and driven at the same time. Unless thes cutouts have spring-return motors, you can't wire them with just a switch. How would you close them once you drove them open with just one swtich? I'd fire two relays with a rocker switch (two normally open, momentary contacts) from inside the car. One relay would allow power (Pos-Red,Neg-Black) to travel from the battery to the cutouts to send them open. The other relay would have the output polarity swapped, then jumped to the first realy's outputs to finaly go to the motors and close them. It's kinda hard to explain without a drawing...I'll try to make one up.

 

The cutouts came with everthing pre-wired, all going to one rocker switch, coming off the rocker switch is a power wire and a ground... I just need to hook them up.

 

If you send them to me..I'll be sure to tell you how to hook them up after I install them.

But like the other guys said run them on thier own system. Don't tap into any factory wiring other than the ground. For reasons mentioned above.

 

You can't run a ground directly to the motors, both wires need to be reversed in order for it to close...so they need to run all the way to the switch. The DMH comes pre-wired. Just use any factory accessory wire, available either at the fuse box, or under the center console.
