I have a 92 4runner, and im fixing up the tailgate today, for the rear defog tabs on the window which wire goes on which tab.. white wire and black wire.

 

anyone?

 

I just looked at my spare rear window and the connector closest to the corner looks to connect with all of the heat sinks throughout the window. The other looks to just run along the base acting as a ground. I would take and get your test light to be sure that the white is the hot lead. then connect them and prey for winter to come again so you know if they work. lol
I am not responsible for any damage you obtain to you or your vehicle as a relult of the advice I have given you though. Please test the wiring for power with the switch on and if you are still unsure of the answer I have given you refer to an elecrical guide. hope you get it fixed.
