got my v1 hard wired the other day. i actually put it on a fuse that is always on. not a big deal to me any way as i always shut it off. my dad has an 8500i and his crapped out. escort told him that it is because he didnt shut it off. i noticed that if i put it on a switched fuse, when you start the car, it sort of turns on 2 times in the start up process. i wouldnt think that the quick on/off with partial voltage as the car starts and all that crap is good for it any way.
oh also many thinks to the people in this thread who posted with their installs and help. it only took me a little while and was very easy to do. maybe ill post up some diagrams how i did it if i get time.
