viper 550h alarm goes when remote start

i just bought a 95 gmc truck that had a 550 h installed, there were some wires cut under hood, put everything back the way that it look like it should go ( length of wire, color, so on ,so on) i got it put back together or so i thoght. alarm arms and  disarms, locks doors and unlocks, led blinks, but when i use remote start it starts truck then alarm goes off  wth!!!!!!!   i did a search and did not see anyone with this problem so here's the 1st post on this. also my dome lights dont work in truck also, same issue or mybe different issue,  ( truck was bought from local police auction, was used for a few years a undercover NARCOTICS  vehicle so this might be why theres no inside lights) would this cause alarm to go off in remote start? do i need to relearn Brain? ( being it was disconneted for a few years)

thanks in advance for your help.

it the same unit, i push 1 and 2 button to remote start, i was thinking is it possibble the alarm is going off because something is wrong with inside lights , loose wire or something. mybe it thinks the door is open or something just a thought. i had found this if it helps you help me http://www.directed.com/guides/manuals/ig/viper/N550hf.pdf

i dont understand all of it, but mybe someone else will also found this http://http://www.viper.com/Support/Guides/Default.aspx                 

i was screwing around with it, no it does some crazy doodie, still does the thing alarm goes off with remote start, but know the new thing when you disarm it and doors unlock alarm goes off with only half the sound ( not all the way loud) open door it goes away. push dome light button in truck it comes back on.  answer to question above when i arm it it goes "wooo wooo wooo" in half the sound ( no chrip), when i disarm it , it "chrips".

i unplugged the brain for a little while, i'll plug back in to see if that changed anything.

It sounds like either the alarm brain or the siren, or both, may be grounded improperly.  I've heard sirens sounding at low volume when an alarm was grounding through them before.  A bad ground would additionally tend to cause other weird problems, so I'd suggest you check that out as well.
