I just R&R'ed my t-case to pull my trans. I have an extra 2 pin plug now that I'm not sure where to plug in. I got the two on the tailhousing of the t-case that read the output shaft that goes to the rear driveshaft. I also got the one that is on top of the front-drive side of the t-case. What am I missing? I couldn't find another place to plug this connector in. I think I was running with one unplugged before, but it doesn't seem right that I would have an extra plug.

 

From the service manual these are all the electrical connections

(4) Propshaft Speed Sensor - Rear
(5) Vehicle Speed Sensor (VSS)
(6) Propshaft Speed Sensor - Front
(7) Transfer Case Encoder Motor

 

Not sure what #3 on that diagram is pointing to, but I don't have anything in that location. Looks like I have everything else on that diagram connected correctly. I wonder what that extra connector is for

 

buwhahah 3 is pointing to the transfer case ummm case.

(1) Fuel Lines
(2) C350
(3) Transfer Case
(4) Propshaft Speed Sensor - Rear
(5) Vehicle Speed Sensor (VSS)
(6) Propshaft Speed Sensor - Front
(7) Transfer Case Encoder Motor

You have an 80E right? Any chance its the speed sensor in it not plugged up?

 

oops
