Where is the Relay controlling the Blower Motor on a 85 300D?

Where is the Relay controlling the Blower Motor on a 85 300D? While I was replacing my center console on my gutted 85 300D, I accidentally knocked the wiring off something. Now my Heater / AC blower fan does not work. I can hear the compressor click but I dont get 12V on the fan motor at the green and brown tap on it. Upstream there is a 8 "Double Contact Relay" but my Haynes doesnt say where it is.

On my '82 300D it's between the glove box and the firewall. I had to remove the glove box liner to get to it.
