Heater control pinout

[dnb]

Does anyone know what pins on the heater controls do what?

I have a partial list, but would like the gaps filled in. The wiring in my Griff is far too customised for me to know what is standard any more - the last 3 wires in my list are not connected to anything, and I don't know if 2 of them are like that from the factory or whether I have removed potentially useful bits of wiring...

There's a 10 way connector:

Black - GND
Black - Gnd for ice detector
N/C
N/C
Green - Ignition +12v
Blue/Orange - Heated mirror output?
Black/White - Ice detector
Pink/Black - ???
White/Pink - A/C output (thanks Mike)
Pink - Heated seat output to relay?

Any futher thoughts?

White/pink is the a/c out.

Just one more to get now. Anyone?

Hi, I'm converting my Griff 400 early window switch type heater controls to the later 4 knob electronic type.
I have a control panel, ecu and all of the syncron motors ect.
Does any body know what the 2 spade type connectors on the ecu are for? are they for the blower? if so is it a + & - connection or does it go via a relay ect?
Does any body have a wiring diagram for a Griff 500?
Thanks
Chris

The spade connectors are indeed for the blower. They are effectively a switched ground. (I.E. If you short them then the fan runs) The fan power comes directly from the fuse board.

Inside the ECU is a FET acting as a "resistor". This is controlled (via crude but effective analog electronics) to provide a variable speed fan.

Cheers dnb.
Do you know how these ecu's switch the heated seats and air con.
Are they controlled via the temp control knob somehow? This is the only way I can see this working unless I'm missing something, if so does this rely on the ice sensor working?
