Rear window defroster

All,
I'm trying to replace my missing rear window defroster. The car is relatively new to me and it was missing. I was able to track down all the parts and got them installed.

I need to figure out where the 12v supply comes in to tie into the switch. In the FSM it is circuit C10-18LGN and tells me to "see accessory wiring diagram". In my manual I can only find the Accessory Wiring Diagram for a Coronet. The dash harness has been replaced and I can find no way to hook up the LGN bullet connector from the switch harness to the dash harness. Not sure if M&H wires their dash harnesses for this option or I am just missing something. Any help would be appreciated.

Isn't 1970 the first year for the two speed blower motor (resistor looks like a heater coil and is inside the blower housing)?

I believe it runs from the switch to the appropriate fuse at the fuseblock and connects with one of those piggyback connectors.

Brock,
  There is a male bullet connector on the light green wire coming from the switch harness. The connector sure looks factory as it has the sealed rubber around it. From the service manual I would agree with you as no bullet connector is shown on the schematic. This is what has me so puzzled (very easy thing for me).

ok after 45 minutes on the phone with Ken from M&H we both gave up. If anyone here has the optional rear window defroster and can tell me where the 12v feed comes from I would greatly appreciate it.
