Hey everyone , I’m currently trying to install a new radio system and it turns out I don’t have sync. I have a 2015 xl . It used to be used by law enforcement and I’m wondering if anyone has installed a sync 3 system into them. I currently have the little 4 inch system installed but have purchased an 8 inch sync 3 system and went to install it “purchased the harness for conversion “ but it turns out I don’t have the “apim” I believe it’s called . And the only power supply I have for my radio is the “fcdim” or “fcim” for it. Anyone figure out a way to install the new sync with only this wiring?

This connected to my 4 inch screen . There was no sync installed behind it .
