Mike ; have you checked back on your other post ? Wiring is for a mid trans sensor that Allison no longer uses. Should be cleaned and covered with a waterproof material.
While your in the transmission area, look for a 7 foot coil of wire on top , with a data connector on the end, grey with a cap, Freightliner supplied it with the chassis harness and Newmar was to locate it. Didn't get done , I ran mine up the trans dip stick tube and hung it inside the engine rear cover .
