I have a relay - C4VF-10B953-A - It has 3 posts. It is attached to a bracket that I was told was attached to the back of the radio. I have looked through all my parts manuals and cannot identify its function or purpose.
So i think the conclusion is it may have been used for something in 64??? There is a long thread on that relay in the other forum, but know real answer. If someone has a good answer please post it.
If memory serves me right it is an Engineering number, this explains a bit why the part in the Autolite, Rotunda or Motorcraft box does not match the part number on the box itself. Ford had two seperate numbering systems....
