Thanks for the terrific information. I just finished installing a Viper 791XV into my 2004 WRX. Everything works great. However, I tried connecting the neutral safety wire to the light green wire on the parking brake switch yet the remote start still fires regardless of the position of the parking brake. I think regardless of the parking brake position, the neutral wire is always seeing ground. I also diode isolated the wire just in case. Has anyone else had this issue and/or found a resolution?
