you can always use a VOM or any external speaker and pin it out yourself. That is how I would try to do it if information is not available.

Hi
Had a Radio Tech help me a bit … And I took the cover off and found that that Model requires An Internal
Speaker wire and my radio was missing this. I found the right plug for the connection inside the radio and
soldiered the other end to the speaker and all works now… :grin: :grin:
Thanks for the help Everyone
