Midland Model 70-1526b?
 

Greetings! Not necessarily a boat anchor, but I was hoping someone
could help or tell me where to get the info. I have a working Midland
model 70-1526b mobile, 450 band. I have not used it and was getting
ready to have it converted when I realized that the red hot wire had
come out of the 10 pin modular plug. Can anyone tell me which hole it
goes into if you are looking at the back in the upright position? I
appreciate your help. Jon. KG4GFU.
