Help finding speedo plug part number

[hear]

While trying to solve my NSS & backup lights problem, I'm finding that just about every plug in the transmission area has the insulation "pulled back" out of the connector, exposing the wires and in some cases leading to a short. I'm trying to source replacement connectors, but the service manuals don't seem to be any help. I looked through the entire wiring & transmission section of the parts list doc, but found no mention of the any of the wiring or connectors in the transmission/transfer case area. The plan is to pull down that section of harness and replace the bad connectors with either new waterproof connectors (that is, non-OEM style) but that isn't possible in all cases.......like the speedo sensor at the back of the transfer case.

So all that to say, does anyone know the part number for this connector, and if so, what resource did you use to determine that part #? Teach me your ways.

Typically I would say: https://www.amazon.com/dp/B004F5BN3O/?tag=wranglerorg-20

But since you have a 97 your plug is probably round holes and not blades. Take a pick of it looking at the front?

If you can't source another connector I can send you mine from when I converted it.

The 97s and the YJs use an old style VSS with an older connector. You're better off buying the 98+ sensor which usually comes with a pigtail you can splice on. That would upgrade you to the newer connector and also get you to the newer, better sensor. The old sensors would leak ATF up into the connection after a while which as far as I know, was why jeep switched in 98.

you got a part number on that?

I did the Mopar kit years ago but it’s since discontinued. Any of these should be just fine. I’d probably opt for the NTK myself.

I guess that solves the problem...splice in a new connector and then replace the other end completely. How hard is it to change out the speedo gear, and will my current gear fit on the newer sensor shaft?

It’s easy. Look in your pic, see the bolt on the speed sensor? Remove that and it will let you pull the old sensor out of the sensor adapter housing. Drop your new one in and bolt it down. That bolt is practically not tight at all so don’t tighten too much. I don’t even think you’ll need to pull the assembly or mess with the gear at all, but it’s been 5-6 years since I messed with mine. I THINK you can just drop the new sensor right in.

If by chance you do need to pull the whole assembly, it’s easy to reinstall as well. If you are, installing a new gear, just pop it into the speed sensor and then clock the number range on the speed sensor that corresponds to your gear teeth to be at the 5:00 position on the tail housing hole. The clamp bracket teeth will grab the speed sensor and rotate it to the perfect right spot for you.

I’ve got a 41 tooth speedo gear in mine, so as you can see my 39-45 section is at the 5:00 position. I got it close by hand, then the bracket made it perfect once I lined up the bolt hole.

12:00 is towards the tub, 6:00 is the floor.

And you can see my old adapter housing is what has the numbers on it, the newer speed sensor went right into it and bolted down. Then the new wiring plugs right in.

I’ve had the whole thing out when I did my SYE, I didn’t realize it was comprised of multiple replaceable pieces. When it came out at that time, it was all one piece all the way down to the eccentric shaft & gear.

Yep, appears to be all one piece but is not. I learned the same when I received the new sensor and saw how small it was. It all made sense once I got underneath to install.
