Backup/Reverse Light Switch

I've seen a few posts in the archives of people looking for the correct switch to use when installing automatic reverse lights on their jeeps. I have a late T90 tower with a reverse light switch in it stock. The switch went bad and I discovered that no one lists the switch for a 1970 cj5 (which had the switch stock).

So to save headaches for any of you looking to install or replace a switch, here are the part numbers and manufacturs that will work:

Standard NS20
Wells DR429
GP Sorensen LT6
Echlin NS6575 (availible at NAPA only)

All are 2 prong and are 9/16", 18 threads per inch.

Here is a link from the Standard website for the NS20 which lists its application (type "ns20" in the part# field). Use one of the years/models listed on this link and the autoparts store should come back with one of the above mentioned manufacturers/part numbers.

I have the T14A....will these work in it? I have heard that they were the same.
I need to replace mine.

 

Yup, same. Factory t-90 w/ switch, t-14, and t-15 use the same one. Maybe others.

 

Thanks william....

 

thanks i did not know that that would work in the t15 also, i gave up looking a long time ago. now i can have reverse automatically instead of a toggle switch!!!!!

 

I have the toggle switch also.......that I always forget to turn off.......

 

The gold is Napa NS6575. The black switch is one I removed from my 1968 cj5 T90 transmission. Transmission is currently being overhauled. The threads on Napa switch are 1/2 inch shorter than black switch. The black switch threads are longer with a jam nut to get proper positioning for shift rod to actuate switch. What my question is will the NAPA switch when screwed into T90 shifter cover, will it go in far enough for shifting rod to actuate switch? The old switch is inoperative.

 

If it didn't, I personally would just find a small piece of hardware (Nut? Washer? Ball bearing?) that would take up the correct amount of space.

 

Can you measure the length of the threaded part, please? I could do a search and find a more comparable switch. I can see that the length (or lack of) of the thread is obviously an issue. If the switch were actuated in a straight linear motion, just adding a longer push rod you could solve the problem. In this type of switch, the shaft of the transmission top slides and pushes the ball upwards just a bit. the thread engagement has to match almost perfectly the wall thickness of the transmission top, since it looks like you don't have a lot of wiggle room. If you install a longer threaded switch, then is just a matter of using a locking nut (as in the pic ) and adjusting the right height. It can be checked with a test light or any meter.

 

Looks like it would use the same connector as brake light switch (which I also need). Anyone have that connector info handy?

 

My Tux when I bought it had a small bracket screwed to the bottom of the dash, it had three small switches on it. One was for the interior light, one went to the back up lights, and the third was not hooked up to anything. Does anyone know if that was stock? I put a Jeep headlight switch on the left side of the steering wheel, first click out is interior light, the second is back up lights. My Jeep had a lot of changes when I bought it, but most of the Tuxedo Park parts were still on it, I have never seen an all stock TP.

I do know that backup lights were not required for new vehicles in 1964. Not certain, but I'd expect if the vehicle were delivered with backup lights, it would have had a switch on the transmission. Have you looked at the top cover of your transmission for a switch location?

 

I would guess no. This image is a late 64 build 65 TP.
The green lines are from a bumper bracket question.

 

I'm pretty sure the bracket with switches is not original. A prior owner added the backup lights as they were not standard until the late '60s. The early Tux's had a column shift, so no shift tower to have a switch. They had a tin top transmission cover.
The hardtop likely had a push switch mounted on the interior light. One of my two Tux's has a factory hardtop with a dome light with the push switch, but I'm the third owner, so there's no telling what was original.

You all three right, it just dawned on me, the box on my Jeep is a 71, and the cowl is a 66. The PO, a friend, had the Jeep for 27 years, put a 71 body on it. The body was pretty far gone when I redone it. I got a nice cowl from a donor Jeep, and made all the floor in the front out of 11 gage, and put 1/8" checker plate in the box.
