The location of the set timing connector is incorrectly called out in "SECTION 6A" of the "Driveability and Emissions" Service Manual.
The correct location of the set timing connector is inside the cab where the heater box and the carpet meet on the passenger side floor. Pull carpet back to
expose the single wire and connectors on the outside of the control module harness. The wire colors are tan with a black stripe.
