Speedo quit no cruise

Checked wires on rear diff could not see anything wrong. Changed speed sensor and still no speedo. Could it be input or output sensor on ******?? Help help help! Feel free to offer any advice.

What year is yours? The rear speed sensor connector wires like to break up near the body

02-05 look at the wires near the body up over the rear diff like mentioned above
That controls the cruise and speedo
lots of times you can not see the break , but ...
Mopar has a kit with wires etc

I've looked but the wires connect to another group of wires. Can they be disconnected there? It's about a foot long to the other group of wires.

It's an 05 with the 3.7 4x4

Why not just test the wires instead of eyeballing it?

cut and splice should be more than a foot long 16/18 inches or so

So I finally got to have a better look at the plug. Once I took off the electrical tape the plug fell right off. Wires were broke but looked perfect. Re sodered the wires and put back together. All fixed up! Thanks everyone for all your input it was greatly appreciated.

That connector on the rear diff does give a lot of problems...glad you fixed it.
As a matter of fact Chrysler issued a TSB for all 2005 KJs that the rear diff may have been factory filled with wrong oil that eats up the sensor.
Fix is to have Dealers drain and clean out the rear diff, fill up with correct oil and replace the speed sensor.
