i found wiring info for a 2000 cadillac sts on this site. is it the same for a 2003. also the compustar system has a wire that disarms the factory theft system for a second when you auto start. do i need anything else to make it work like some sort of module. thanks for help guy this only the second time i installed my self.  i fried the system the first time.i think what i did wrong was hook the negative pulse horn wire to a positive horn wire.because i had it all working fine till i hooked that wire up.i got the wiring info off here. it was a 1991 accord i put it in . i should of checked every wire with a multi meter. any help would be greatly appreciated.i have found some info on data bus modules that do locks and windows and other options but the alarm does all that.is there a simple pk3 bypass i can use. thanks guys any other tips or help  for this car would be great. its a compustar alarm starter cm3000 i want to install

You have to use a passlock lock bypass module. If your using compustar i suggest you use a GMSL2i Version 1.9.
