I bought a used DMH cutout from a friend of mine, and got around to installing it today.

Well I'm not sure if it just doesn't work, or if I'm wiring it wrong.

I have a black and a white wire coming from the cutout to a harness with 4 plugins. The black and the white from the cutout, and I'm assuming a power source and its negative?

Or is one supposed to be a ground? If so is it the black directly from the cutout that is the ground or is it a ground that I hook up myself from the harness?

 

I'm assuming he didn't gave you the switch/harness,there should be ground and power going into the cutout and the harness will reverse polarity so the motor will move both ways.

 

Yes the switch came with it, but I need to know exactly how to do the wiring.

It is a 2 wire cable from the cutout itself.

Does the black wire from the cutout itself go to a ground? Or do those 2 wires go directly to the 4 wire harness and the 4th wire from the harness goes to ground?

Or is there only supposed to be 3 total wires used?

I don't know how to wire this for sure...to know if the cutout doesn't work, or if I'm wiring it wrong.

this is an earlier cutout harness so its not quite the same as the more recent ones.

I have tried it a few ways and had no luck with it working

 

Tabs on the back of the switch:

A b
C d
E f

A- battery pos
B- ground
C - Cutout black
D- Cutout white
E- ground
F- battery pos

I typed this on me phone so its a bit.cumbersome, but will work.

 

My switch has heat shrink on the back that comes out to a 4 wire plug.

the colors of the 4 are green, red, black and white. Only the black and white don't match up to the black and white on the other side of the plug for some reason. The green and red come out to the black and white from the cutout.

So not quite sure how that changes things.

 

Take the heat covering off so you can see the tabs on the switch. All you need is a DPDT switch, it doesnt have to be the one that came with it. Hook it up as a described above.

 

So it needs both grounds and both battery positives hooked up?

 

Yea, or just share a single wire for the positive and one for the ground.

 

Got it working now.

Thanks a bunch for the help.
