yes you can, I just put on in mine, I did have the conector and used my 4 pin found the ground and then pos on my conector and wired it in. The mirror is always hot, so you just have push the mirror and compass button when you get in and out of the car, I will be wiring up a temp sensor soon too.
On the 4 pin I used black for ground, Orange 1 is positive always, orange 2 is for interior light, and brown is for parking lights. I added extra led lights for more light inside the car since the mirror that i got did not have map lights on it.
Good luck
