That should be OK. When you insert it into the housing, if you twist it around it should drop in fully. You should know when you get it: it will make a big difference in depth and you should be able to feel more resistance when you turn the gear by hand.

OK, as long as you had the correct installed position (rotated so the proper number stamped on the sender unit is aligned with the dot) then we now know it is an electrical problem.

Check the voltage on the wires at the speedometer wires on the transfer case. Make sure the ORG wire is hot when the key is on, and the BLK wire is grounded. Those are the easiest two to check.

I think as long as the bracket goes into the notch, you are good to go.

That was just the easiest thing to check for, Better move on to looking for electrical causes now.

Been awhile..got busy with work and had to take a break. Anyway i checked the electrical system.

White and orange under dash and on tcase have continuity with each other.

Black under dash has continuity to ground.

drk blue/white has voltage with key on.

Black on tcase has continuity to ground.

Orange on tcase does not show voltage to ground with key on when using test light but when i used multi meter set to DCMA it shiws 4.46.

At the transfer case:
The Wht/Orange at the transfer case should show 4 to 5 volts referenced to ground with the key in the ON position

Orange should show 7 to 8 volts when referenced to ground with the key in the ON position.

Black should show continuity with ground (looks like you have that one correct)


Next, pull the wiring harness off the vehicle speed sensor on the transfer case. With the key in the ON position, Get a paper clip or spare wire and jumper the Wt/Or wire with the Blk wire. Connect and disconnect them rapidly, does the speedometer flutter or move while you do this? (You are doing this to the wire side that runs back to the cab)


If those all look correct, then we can check out the under dash wiring.
