Default Rear Window Defog Wiring 71 Camaro

I'm restoring a 71 with the rear window defog option. The original switch had apparently failed sometime back and someone attempted to hack in a standard 2p2s toggle switch with an indicator light. My guess is that didn't work so they hacked out the wiring. Does anyone have a wiring diagram for this option? The diagram i purchased as a suppliment to the assembly manual shows no options. I purchased the new replacement switch and it has 3 round pins on the backside...help! Thanks

3 position Sx - Off, Low and High - 3 Connectors - 12v Power Source - Low-Spd and Hi-Spd. The Low-Spd run through a Ballast Resistor (Dodge Ignition Resistor will do). Circuit is complete when grounded at the Rear Defrost Fan Motor.

My defogger system is the embedded resistance heater wire in the window. I found the lead from the window to the IP area with a bare end and a fused red accessory wire with no end. I'm trying to piece together the rest of the puzzle.

No Embedded Rear Window Defogger rear Window Screen exists between 70 an 73.

After that who gives a Sh*T

Must have been a sought after enhancement in Fargo South Dakota. I have a latching countdown timer and a relay...think I'll make her functional. Thanks for the info

No such thing in my opinion. Maybe a 70/74 rear window aftermarket.
And if anyone has a 70 Rear Defog Trough Motor to Rear Deck Plastic Housing & Bezel, I am interested it purchasing it. I believe the 69/70 Cadillac and Tornado items are the same for the 70 Camaro Rear Defogger Interface.
