I posted this back in 2011, it might help....
Why people are getting flat batteries;
I've seen this posted twice recently and people don't appear to be following the alarm manufacturer's instructions.
An external anti-grind/starter relay should be wired as follows:-
85 Only use the "ground when armed (GWA)" from the alarm.
86 Ignition 1 only*.
87a Key side of starter
30 Starter side of cut wire and starter output from R/S.
Diode 1N4004 across 85 and 86 with the band towards 86.
*If you join a constant 12V+ to 86 that relay will be on all the time and you will have a drained battery within a day.
