H1/10 normally open interrupt input #2 and H1/12 normally open interrupt output #2
These wires can be used for fuel interrupt or ignition kill. The H1/10 and H/12 wires are interchangeable, so it
does not matter which half of the interrupted wire they are attached to. Both interrupt wires have continuity
when the ignition key is turned on and have no continuity when the key is turned off. If the alarm is armed or
triggered, the interrupted circuit will remain interrupted until the alarm is disarmed with the remote or overrid-
den with the siren key lock.
To connect the H1/10 and H1/12 interrupt wires, first you must locate the ignition or fuel wire in the vehicle.
Cut the ignition or fuel pump wire, and connect the H1/10 wire to one end of the cut wire. Then connect the
H1/12 wire to the other end of the cut ignition or fuel pump wire.
NOTE: If the on-board relay were to fail, the circuit would remain interrupted until the unit is
repaired, bypassed or replaced.
H1/11 (-) siren output
The H1/11 wire connects to the siren input wire of the 515E siren. (The siren input wire is labeled with a GREEN
tag on the siren harness.) The siren duration is programmable for 25 or 50 seconds, if programming the unit with
the Valet switch. If using the Bitwriter for programming, the duration is programmable from 1 to 180 seconds.
Connect the siren's BLACK tag wire to (-) chassis ground, preferably at the same point you grounded the control
module's H2/3 ground wire. Connect the siren's RED tag (+)12V input wire to a good source of constant 12V. Refer
to the H1/6 Siren Data Wire and the H1/4 Hood Pin Input wiring descriptions in the H1 Harness Wire Connection
Guide section of this guide for instructions on wiring the remaining siren wires, or refer to the side panel of the
515E siren's box for detailed instructions for wiring all of the siren's connections.
H1/12 normally open interrupt output #2
Refer to the H1/10 wiring description.
