Heres the dealio i just purchased a 2003 focus zx3 with this alarm installed . When i went to pick it up yesterday and the guy did not have the keypad and had to pull a fuse out of the units harness to get it to start but on my way home the battery dummy light came on would this fuse being removed cause my battery to go dead or give me a false reading on my gauges? Long story short how do i go about just removing this system and put it back to stock .
