I need the wiring diagram which show the 13 wires plugged into the speedo / dash digital display

SOURCE: Wiring harness diagram

Your question is not clear, 2002 trailblazer has a towing harness, in order to find each wire, use a ohmmeter and try out each application.

In case of male harness of a camper you can test it with 12 volts in each wire looking which light is on and if it is different position cut wires and make similar wiring

The location of the speedo sensor is on the top of the gearbox case, behind the rear cylinder. Thier speedo's are electronic and not cable driven, so are not driven off the front wheel.

I hope this helps..
