Adding Reverse Lights

[papakb]

When I mounted the new neutral start switch into my shifter to use for the backup lights I took the switch to the local hardware store and matched it up with the switch threads and the shifter threads. The part was an off the shelf brass reducer with standard pipe threads. I did cut it down a bit so everything fit properly but there was no major rework required.

Something else that I found on my truck was the shifter boot already had a nipple on it that the wires would fit through and all I had to do to seal it up was to put a wire tie around it.

Nomad1, Military vehicles tend to use standardized Packard connectors across the board so what we have on the HMMWV is going to match what you have on the deuce unless yours is a very early truck that still uses the metal bell style Douglas connectors.

I got a Humvee ambulance reverse light switch and had to have a small bracket made to hold it to my new to me 4-speed shifter.

So now like every other car in the world I put the shifter in reverse and my two square LED reverse lights and center mounted / under truck light bar come on.
Works like a champ..

Looks like a marketable product to me!

Hope it does not start any parking lot fist fights I would suggest putting a switch inline to disable them - good luck

I live in Chicago, it takes a lot more then some bright reverse lights to start a fight around here..

You going straight pipe exhaust?

We ditched the muffler and high temp exhaust wrapped the entire exhaust and added a 4" tip.

I still have yet to drive the truck with all the new changes and if I happen to not like it straight piped I will add a muffler back to it.
We shall see..

Maybe won't be that bad, but bad, CAMO

Once the truck is done and back in my possession I will take a bunch of videos, no worries !

Your LED lights don't draw that much power so what I did was to tap into the circuit that lights the shifter lamps. That way if I don't want the backup lights to come on I just leave the dash lights off. The other advantage is that wire is already in the shifter.

 

[Milcommoguy]

Not to sure that's the place to tap. The bright, dim, off setting in the "battle lighting switch" uses a small wattage resistor in the switch designed to handle the "DIM" for the dash lamps and shifter LED. Not so sure ?? of what lights SS users are working with and even LED (couple of cheap 20 watt'ers) could pose a problem in the dim position. My concern is toasting the resistor in the dim position.

See TM -20-3 electric prints, page F0-1

What ya think papakb? CAMO

View attachment 715084I had an old post were you just buy a switch and install it on the shifter, you do not have to remove it, just go underneath and cut a small hole in the boot
This is what I have for back up lights, a bit more time, but you get what you put in.

Lou, what circuit did you tap for these reverse lights? I don't want to tap into the instrument panel lights because I want to use them without the reverse lights turning on.

My recommendation for almost anybodyted the new neutral start switch into my shifter to use for the backup lights I took the switch to the local hardware store and matched it up with the switch threads and the shifter threads. The part was an off the shelf brass reducer with standard pipe threads. I did cut it down a bit so everything fit properly but there was no major rework required.

Something else that I found on my truck was the shifter boot already had a nipple on it that the wires would fit through and all I had to do to seal it up was to put a wire tie around it.

Nomad1, Military vehicles tend to use standardized Packard connectors across the board so what we have on the HMMWV is going to match what you have on the deuce unless yours is a very early truck that still uses the metal bell style Douglas connectors.

My recommendation is almost anybody working on these old green gems is to buy a pack of 50 to 100 of the packard connectors or go in with some fellow green machine addicts and buy them and spilt them up

For my reverse lights I ran a wire up to the horn in the front. Used a Y splitter so I wasn't cutting any wires, and hooked in on the input side of the horn. horn works when the button on the steering wheel grounds the system, the wires at the horn are live whenever the switch is in the stop light or service drive position, and off for the other 3 positions of the top switch.

Easy to tell which is the hot side of the horn. Disconnect one of the two wires for the horn, measure voltage with switch in stop or service. If the wire on the horn side has power, it's the wrong one.

I mounted mine on the antenna mounts and run them via a switch. Also have a back up alarm on the circuit.

Lou, what circuit did you tap for these reverse lights? I don't want to tap into the instrument panel lights because I want to use them without the reverse lights turning on.

I just took a feed that is on when the key is in the on position, it's been a while so I'm not certain which circuit, the lights that I use do not draw a lot since they are LED's
