Guys. I'm fairly new and a bit confused on the back up lights. Is there a thread that shows how to install the switch? Do I need to add rear lights as well or will tail light go bright while in reverse? sorry for these basic questions.
If you do not have a light installed already, then yes you will need to install some. The taillight will not turn white like normal cars, or at least i have not seen them. A cheap set of amazon led fog lamps works well. The neutral switch, like I used, in installed in the shifter mechanism itself. Upon removing the shifter (like the original poster of this thread) you get much better access to the underside where installation takes place. The neutral switch has threads on it that match up to a position on the underside of the shifter, so that when you put it in reverse, it will hit the switch, thus sending power through the wiring back to the lights. You can also hook up your wiring at this time when you have some access. Find the wire for your rear service(tail lights, not brake lights) lights as they go back to the rear of the truck.
I don't know the number on the wires, someone may chime in with that info. They should have a crimped metal tag indicating the number of the wiring diagram. I just followed the wires for the taillight up the frame underneath to where it got close to the shifter. I added a splice to that wire, using stock military connectors to match up to the neutral switch. Used heat shrink tubing and plugged them in. I grounded the lights at the frame where the lights were attached. So after turning on the service lights, when you shift into reverse, the backup light would then use the power from the tail lights to activate the back up lights.
Parts wise, search for a "neutral safety switch hmmwv and backup led lamps or fog lamps" you can find them on ebay and amazon. Gear-report also had a few switches for sale recently he may still have some. You'll need some packard connectors for the wiring splice as well if you want it to look "factory." You can also get those on the same sites. I spent about $60 i believe for all items, and i splurged on the super fancy led lamps.
Hope that helps.
