Found some of the original harness I believe. They were mostly cut and were crammed wayyyy up under the dash. I am not sure what some of the connections are for radio, speakers??? I'll upload some photos with some questions.
These are the wires I found today.
1. yellow and brown
2. black/blue stripe and brown w/connector
3. blue/black stripe and w/brown/connector
4. yellow/red stripe and black
--------------------------------------------------------------------------------------------------------
Here are the two I am not sure of - not using but am curious what they are.

yellow/red strip and black
Tested for power constant and switched/ACC and got no readings - couldn't find any other posts describing yellow w/ red stripe along side the black wire. Not sure what these wires were used for. Let me know if you've come across this before. I assumed it was for power but wouldn't use anyway - running a direct line to the battery.

yellow and brown
Tested the yellow and got a reading with the ignition on (ACC). No reading with ignition off. Brown I assume is ground.
I found one post out of 100 that had the same yellow wire being used for ACC. Found here:

Question for everyone:
Would this wire be fine for my modern stereo as the ACC wire??? Very very conflicting opinions...
I did a primitive dry run and hooked things up and everything worked well. Just concerned about draw on the wire with a modern head unit vs the original equipment.
I will be running a fused wire (15a - debated on 10a) directly from the battery and not quite sure about using the original harness with this new head unit even as an accessory connection.
Would love to get rid of all of this original wiring but will clean up and keep under the dash - learned the hard way long ago not to just cut stuff off to clean up wiring
Finally got a new heat gun and will start working on new wiring...will check in here for new input.
Can't thank you guys enough for the responses already. Probably should have documented this more with photos and images of wiring diagrams. Hopefully this will help others down the road.
Again, thanks guys!
