I am upgrading the aftermarket radio in my '86. When I pulled the unit out there were three cables and a light that were bundled together with the wiring harness.

I've got the wiring for the head unit sorted out but would like to know what these are for. TIA

the ones with the flat blade and pin are speaker wires, the light is a light .. makes sure your lights all work for your hvac controls as they often pop out... the square one im not sure.

I think that square connector might be related to the factory fader control in the center console,

The square plug is not audio. It’s the Auto heat control module hookup on the loom. Guessing you have handles and manual like me. Right side pic are stock DIN speaker hookups, and I’ll bet that light is your Fan icon blower light that popped out. Just pop it back in.
