Rattler Led install

hi there, I hooked up the led scanner, Just went off the wire harness of the rattler 300, know I was wondering do I have to fuse the scanner?  If so what size fuse.  another question after I had the alarm installed by Krazy Krazy , I asked where the valley switch was, I was told they do not install them because the alarm could be shut off by thiefs, but I think the alarm came with one.  I never seen the contents off the box, but I read on the internet that a valley was included.  Does anyone know if this is true.  So I can question Krazy Krazy?

Your led shouldn't need a fuse. That led is just a visual aid to tell you the status of your alarm ( armed or not armed). It does come with a valet switch. I just installed the same alarm last week in my truck. I have a copy of all the contents that came in the original box from the instruction book. If you would like me to e-mail you a copy of this, e-mail me with your e-mail address at jnkml230@cableone.net
