Rear window defroster wiring.
I need help with my wiring.
When I got this car, the wiring to the rear window was all screwed up. The ONLY wires I know what they are in the back, are the third brake light.
I need to know what wires are for the rear defroster please. The window was changed, so I can't use the stock ones, but I bought a small fan/heater that I was going to wire in with a relay, using the stock wiring to turn it on/off.

The hot wire went to the Left Hatch Support.
The ground wire went to the Right Hatch Support.
You can use any ground wire.
If the hot wire is no longer visible because the PO removed it when he changed the window, you might still have the feed for it in the left rear of the car behind the plastic panel.
The wire is a 10AWG purple wire with a White stripe.
