I used the Alpha 12 circuit controller(used all 12 but it is expandable). Originally I wanted to do something like
@sscappaticci68 (nice job btw) going overhead with the controller but ultimately decided to mount in the center console using an RLB rugged radio dash mount....the mount worked well however I believe I would have been happier going overhead with the controller.
To save some dash accessory space I mounted the SDi Eclik on a "pod" mount. I had a friend 3D print the plate for it. That worked well for me having it on the left side and being left handed.
If you decide to use Rugged Radios with intercom definitely opt for the "remote" head intercom version. this will require one accessory slot.
I added some buttons to the steering wheel for horn, PTT, and E-clik oh shit....that saved dash space as well.
After all was said and done I have one blank slot left on the dash!
