COMPONENT TESTING - CONTINUED
This is a typical test procedure for a wiring harness. Refer to wiring
schematic (page 4-37).
Step 3 is a continuity check. Use the following charts to identify
each individual wire in the harness.
Connectors J2 and J3 referenced in the TERMINAL DESIGNATION
column below reference the connectors on the junction box that
mate with the intervehicular cable that provides power from the
towing vehicle. Mating connectors P2 and P3 reference the
connectors on the intervehicular cable. There are no blackout
lighting circuits associated with the 12-Volt commercial wiring circuit.
