DISCONNECT POINTS
Wiring harnesses, cables and leads that terminate at removable plug-in connectors and
receptacles, interconnects the various electrical components.
The cables, leads and harnesses
are fastened to the engine and/or transmission by means of tie wraps and loop clamps which
are secured to tapped pads and brackets.
The wiring harness to vehicle interface connector mounting brackets (on Models 2CA and
2DA) are located at the top of engine.
The wiring harness to vehicle interface connector
mounting bracket (on Model 2DR) is located on the left side of the transmission.
The interface
location provides a means of quickly disconnecting the electrical circuit from the vehicle.
CIRCUIT DESIGNATIONS
The circuit numbers assigned to the electrical circuits are listed in the following table.
Each
harness, cable and electrical lead has a numbered band to identify the circuit.
The band
number is shown at the termination of each circuit on the wiring diagrams following the table.
