    The timing mark scale is at the timing cover and crankshaft lower pulley and can be seen with a timing light. The set timing connector is a single wire connector (tan with black stripe) that needs to be disconnected prior to the adjustment to timing. The wire is near the PCM connectors in the passenger compartment. I think near where the carpet meets the firewall area.
