Junction Block: Operation

All of the circuits entering and leaving the Junction Block (JB) do so through up to five wire harness connectors, which are connected to the JB through integral connector receptacles molded into the JB housing. Internal connection of all of the JB circuits is accomplished by a printed circuit board. There are also two separate wire harness connections to connector receptacles that are integral to the BCM. Refer to SYSTEM WIRING DIAGRAMS for additional information and the location of complete JB circuit diagrams.
