backup light switch

[86sa]

Does anyone know the napa part number for the backup light switch that fits the th400 shift selector?

 

[infidel got me]

Napa part # ns6497 cost is 16.42

Theres no napa switch.
Military switch 12338435

Why wont a rev.switch for a 400 work?

The trans has nothing to do with the reverse switch. The correct parts attaches to the shifter and has two waterproof plugs on it.

Learning about the Humvee as I go. Now I know what to get for my reverse lights to work. Thanks for pointing me in the right direction.

Cole hersee has a switch with the right size thread and two sockets on the back, napa has a similar switch also. My intent is to solder two wires to the switch and encapsulate the back of the switch. Waterproof connections are available if that is what you want-however you're making your own harness anyway because the existing harness does not have connections for backup lights. Cole hersee part# 9162 napa # ns6582.

Upon looking at the posted mil part number (thanks), it seems the same can be acquired from Summit Racing for $30 and includes the bracket which holds this detent switch, making it an easy install.

Here is what she looks like installed:

That summit part is listed as COLUMN SHIFT.

Well that's another way of doing things. looks like it would fit a number of transmissions.

Here's the shifter.
The upper switch is a neutral sw., lower one is Rev. switch.
The hole in shifter for rev. sw. is bigger, thats why they use a bushing as seen in photos.
Bushing outer diameter is about 3/4"

Greg, aren't the switches different electrically as well? One normally open one normally closed.

 

[86humv]

Nope...both tested normally open.

Do the Humvee shifters already have this reverse light switch bracket or do you have to make/ source one?

There is a pic of the humvee shifter 4 post above. It has the threaded holes.

I did see the shifter in the post, but that is not the question that I asked.

There is no "bracket" to mount the switch to in the humvee, so there is nothing to have to make. The switch screws in the hole of the shifter. as seen in the pic above.
So, to better answer your question, what bracket are you talking about? there isn't one.

When the shift lever hits the ball at the bottom of the switch, it completes the circuit.

Sorry for being so stupid and asking a question like that. As I do not have a Humvee shifter in my hand or have I had one out. The shifter looks like it could have had the rev.switch BRACKET bolt to it as a add on that may have or have not come on every military Humvee ever produced. One day when I am as smart as you I will never have to ask such a stupid question. Thank you for your wealth of knowledge.

I was just thinking too hard. there was a pic of a humvee shifter with a threaded hole and a sensor sitting beside it. most of us do not have a shifter to look at. That is why 86humv posted the pic.
Someone stated earlier that there is no aftermarket part for this switch.
