79 defroster wiring

[MZ3 SBC]

After removing the rear window, I noticed the wires all removed from the window trim and clipped at the base where they go through the engine firewall.

Does anyone have a picture of the proper way to wire them? I have read some conflicting posts.

Does anyone have a complete set of wires that they would be willing to sell ( perhaps in a track car conversion the rear glass was changed to lexan?)

Thanks

I think the '79 and '84 have the same wiring for the rear defog.

Look at the elements embedded in the glass to determine which is 1st stage and 2nd stage. I think the 1st stage would be the group of elements lowest in the glass and the 2nd stage the remaining elements.

Here is the '84 schematic.



Getting the wires into the groove of the rear glass rubber and cutting a hole for the wires to exit the rubber and then through the firewall can be a trick.

Someone on the forum should have the wiring harness.

Hey,

Took these photos while I was disassembling mine. The car is a 1980 US model. Hope you can use them.

Does anyone know the recommended gauge for the wires to the defroster?

No Idea on ht wire size...

14 AWG is the closest to the metric wire size originally used.
