I had another grumpy old man moment this evening.
I got the radio extracting tools to work on our Ford. The trick is to slide the tools in until they engage, then push the handle parts to the outside. This evening I managed to get the radio/environmental control assembly out of the car:
The way that radios used to be made was the back had separate connectors for power in, speakers, standby power (for the clock), and the antenna connection was a separate coaxial connection, sort of like this one that I got off of an old radio:
That's what the Sirius FM adapter is designed to work with.
Well, the Ford Motor Company doesn't want to make this process easy. The connector for the radio is a proprietary pin connector with no separated antenna connection:
So I'm going to have to be clever.
