Power/IO Cable Connection
The Power/IO cable is used to connect to a truck’s Diagnostic Connector. It provides both
power and the necessary vehicle data for the MCP50 system. There are two masterpacks:
one with 9-pin Power/IO diagnostic connector and the other with 6-pin diagnostic connector.
A separate lead is on the Power/IO Cable designated for ignition. This lead will need to be
connected to a 12VDC ignition switched power source.
The appropriate 6-pin or 9-pin Power/IO masterpack should have been ordered for your
installation. If the Power/IO Cable connector does not mate to the truck’s diagnostic
connector, the Y portion of the Power/IO Cable will need to be cut off and wires will need to
be crimp spliced. See Chapter C: General Wiring and Installation Guidelines for instructions.
Connecting the Power/IO Cable
1. With the truck’s ignition OFF, remove and push back existing truck diagnostic
connector. Check connector to verify it’s clean of debris and there are no bent pins.
2. Connect the Power/IO cable connector to the truck’s diagnostic connector. Verify the
outer ring is twisted and clicks into place so the ends do not become unconnected by
accident. Verify by pull testing the connector.
