I am going to be hard wiring my Escort Passport Max directly to my fuse box in my 2014 Lexus I350 F Sport. With that said I'll be running the wires along the headliner and for a clean install I would like to run the wires through the mirror stem. Anyone know how to take this apart? I am sure I can mess with it but would rather get some insight to prevent me breaking anything. Any tips/suggestions are welcome.

Thanks
