@ Michael – That maybe the power antenna trigger. A volt/ohm meter can be used to see if it get a shot of power at on/off cycle which should verify. I believe that’s what the antenna is looking for as it’s switch.
Also, what is the small connector block next to the main connector block? Is that for remote cd changer?
