Oil Filter Removal- TR-6

Due to the possibility of a short circuit occuring during the removal and/or replacement of the oil filter assembly, it is suggested that the electrical terminals attached to the oil pressure sender unit are disconnected.

The oil pressure sender unit on 1973 vehicles also incorporates a switch which activates the anti run-on device; and because of this operation, one terminal (the white and purple lead) is "live" at all times.
