Heater power and radio power

Think I have it all figured out. Did the tr6 come pre-wired for power to the
radio?  If so, did it happen to be a white and pink wire?  I found a melted
wire that I believe was for the radio.  Also, where does the power for the
heater fan come from?  The only thing I could find listed was a Green wire
but I don't see any available.   The DPO was using a new wire he had placed
to the fuse box. I would like to go with the original if it's still there.

 

 

Thanks,
