Another Heater Blower issue 1992 RRC

Hoping someone can help with wiring a heater blower in a 1992 RRC

Had it for a few years and have never had fans on AC or heat (already tried changing the resistor) before taking everything out i have noticed the main connector has 5 wires going to the heater but only two connecting from the loom (black and white/grey going to the red and black to heater) nothing is connected to the green, white and orange going to the heater assuming there should be?

There are no lose wires so not sure what has happened before I got the car. There is the clear connector that looks part of the system but all connected.

Not sure how 1992 differs from 1995, but here's the later diagram with pin & colour info:

Thanks Pete, much apricated.

I will double check with the loom in front of me but reckon they probably changed the blower and wiring for the soft dash (1992 is the hard dash).

Look for “RAVE All Models” version. It’s got lots of Classic RR stuff
