76 911 heater lever wire

[john maples]

Hi,
I am trying to sort the heater system and have found no wire to the micro switch at the heater lever. I understand that this activates the blower relay in the engine compartment.
Could someone tell me the routing of the wires to the micro switch at the heater lever?

Thanks,
John

Never Mind -
I pulled back the carpet behind the heater lever and found the wires coiled and ends taped. Evidently the PO disconnected them when the micro switch went out.
Brown wire with white hash marks is from the engine bay, which is grounded thru the micro switch to the chassis thru a brown wire.
