SUBJECT: Special Tools: Bridging Switch/Cable Assembly Oxygen Sensor Socket
To test electric fuel pumps in the car for correct fuel delivery, the fuel pump relay has to be removed and the terminals no. 30 to 87 (or 87 b) bridged on the relay base plate.
Since it is possible that
a) sparks may occur when bridging these terminals with makeshift connectors, and
b) fuel fumes may be present with the attendant fire hazard, a bridging switch/cable assembly has been developed.

For easier removal/installation of the Oxygen Sensor (lambda) with its captive wire lead, a new socket has been developed.
