3.6 Connect the RFLM-4-x Harness to the EDC Connector and to the Resistive Fuel
Level Sensors:
Route the appropriate resistive fuel level input wires (for the number of tanks to be monitored) in the RFLM-4-
x harness to the EDC Bottom Connector. Plug the wires into the appropriate resistive fuel level channels. The
excessive wire can be cut and spliced, bundeled and tie wraped up or cut to length and new D-Sub pin installed
(see the “Working with Connectors” section of this manual for more information). Route and connect the
corresponding wires in the RFLM-4-x wire harness to the appropriate fuel tank sensors. Route the red wire (in
pin 1 of the RFLM-4-x connector) to the aircraft bus via the MVP/EDC 5-amp circuit breaker.

3.7 Connect the EDC Harness to the Capacitive Fuel Level Probes:
Route the appropriate capacitive fuel level wires (for the number of tanks to be monitored) in the EDC har-
nesses to the capacitive fuel level probes. Cut the wires to length, install the appropriate connectors (see the
“Working with Connectors” section of this manual for more information) and connect to the capacitive fuel
level probe.
Note: Note: Note: Note: Note: The capacitive fuel level channels are shared with the resistive channels. A single capacitive and
resistive channel cannot be used simultaneously.
