The timing connector, which can be disconnected to return engine timing to base for adjustment purposes, has been moved from the engine compartment
to inside the cab. This new location is not currently reflected in the Service or Owner's Manual.
The new location is under the dash directly below the glove compartment. The tan/black wire is routed for a short distance outside of a large wiring
harness. This large harness is routed between the heater blower motor and evaporator case. The timing connector is taped to the wire bundle (Figure 1).
