everything is inside the owners manual. i just wanted to add that.

 

a dump is an exhaust dump or cut out which ever u prefer to call it, all u need to do is runn the wire up the a pillar and through the tube thats holding the sunvisor up to the roof then from there its just taking apart the homelink and seeing what ends to connect things to.
pretty much i dont have a garage to keep mine in so i figured i will never use it and can just change it up a little bit.
