Car Alarms: AutoStart horn output, saturn sc2, resident technicians

Question
Hi. I have an AutoStart AS-1755 in an '02 Saturn SC2, but the installers did not connect the module to the horn output. So, the panic and alarm functions (the literature says there isn't an alarm, but there is) simply flash my parking lights, but don't provide an audiable sound. The wiring diagram doesn't specify which wire should be used to connect the horn - none of AutoStarts remote starter diagrams do apparently - and AutoStart won't reply to e-mails... Can you point me in the right direction? Thanks.

Answer
On this one, the best thing here is
to go to my installers forum at
www.installsupport.com and see if
my resident technicians there can assist
with this project. I don't know
this system and can not advise you properly.

Good luck there.
