Got a couple questions about a speaker hook-up. I have a '51 Ford radio. It has a three pin plug for the speaker on the right side with three wires going to the speaker. I realize that one of the pins must be for a ground and another is the "hot" wire but what is the third pin for? And, is it necessary when going to a modern speaker requiring only two wire hook-up? Thanks Tom

The third pin just locates the plug in the socket. There is no wire attached.

Hi Richard I have added a picture to better explain my question. As you will note in the picture each prong has a wire attached to it which goes to the speaker. On the speaker end the yellow and blue wires are soldered together. The green wire is separate. I guess what I am asking is why two wires connecting to the same post? What does this accomplish? Thanks Tom

The 3 wire plug was used in a radio with the fader control for the rear speaker built into the radio. Most Fords had this type of radio in the early 50's. If the radio did not have this feature, only 2 wires were connected internally to the plug. If the radio had the feature and you only had the front speaker, the speaker wires were soldered at the speaker so the fade control would not cause the one speaker to go quiet. Tom

Tom- That's the answer I was looking for! I had several suggestions but you hit the "bull's eye!" Two speakers were an option on the Victoria but this car had only one speaker which explains why two of the wires were soldered on the speaker end. Many thanks!! Tom
