1993 Rear ABS Sensor Wiring Diagram

[projectRanger93]

Working on my '93 4.0L 4x4, all manual, that i bought from Copart and I took off the bed to change the fuel pump. I noticed the ABS sensor wires on the rear differential were either cut or chewed off a foot and a half from the sensor. Does anyone have or can point me to a wiring diagram, or can tell me where it's supposed to connect to? Is there an intermediate connection somewhere?

Thanks for the help!

P.S. how often do those ABS sensors need to be replaced? Since i have the bed off, should i just change that too?

Since I didn't find any solid info online I ended up buying the Electrical & Vacuum Troubleshooting Manual (EVTM) for my year and it had all the diagrams i would hope for. Attached are the Rear ABS (RABS) diagrams for anyone dealing with the system themselves. The sensor measures around 1400 ohms, which one can test from the RABS Test Connector (C140) located in the engine bay (assuming none of the intermediate wiring is cut like mine was). If it's nowhere near 1400 ohms it needs to be replaced.

I measured my sensor's resistance and it was 1.36 kohms, so good enough. I soldered my wires back into the main harness and my ABS light turned off. Success!
