Blower fan resistor wiring diagram.

Does anyone have a diagram for the blower motor, relay and resistor wiring? Some idiot, (me) removed the resistor years ago to clean things up and now I want to put it back. I have 3 or 4 wires that are cut where they came out the firewall under the heater box but I cannot find a proper diagram with the matching colors.

Thank you.

Here is a diagram showing the blower motor circuits

PS, where the HVAC wiring says "manual" that refers to the non digital controls version (regular "manual" dash VS the electronic digital dash)
