With two differences my story parallels yours.
Different size wire (I think not sure really)
Pioneer dash radio instead of a Panasonic.
NOTE: the radio fuse might not be the radio's fuse, Here is why.
The chassis maker provides a fuse marked RADIO and a terminal where the body builder is supposed to connect the power lead to the radio.
The body builder technician who installs the radio might not have read teh chassis manual.
In my case Radio is, in fact, radio (Well it is now) but the Air conditioner is, something else. (That is a much bigger wire).
