Found this trio of wires behind/under my radio...looks like they are tied in a knot and some type of old heat shrink was installed. Could this be from the factory and for an option that I didn't get?

Heater Resistor Plug wires perhaps.

Model year? Do you have an aftermarket radio? Wire colors look like those used on the final audio output of a stock radio. Post a pic of the heat sink. Does it have a big 501 transistor in the middle of it?

Easy Mike, I did find the 501 transistor and the wires come down to a plug that is still intact. I do see now some more wires in another group that are laying across the trans hump and wires of the same colors are cut!
Pics are coming ....






Car is a 1968 and had an after market in it when I bought it.

Hi S,
The other (passenger) side of the radio.
Headed as HF indicated. You can see the wires ducking down the back side of the heater box.

Alan, so you are saying it does go to a heater resistor?

Colors in my AIM show correct for heater something.

I see it on my doc rebuild sheet....I just need to go find it on my car now, hopefully the plug is still there!

Thanks for the help guys!!

Hi S,
Yes.
In the 71 AIM it's shown on UPC1, Sheet M1, View A, and UPC 12, Sheet B5.
The B5 drawing gives a hint at the shape of the connector that appears to have been cut from your wiring tail.
Regards,
Alan
