more than the 1 amp output that the Brown wire supplies. One alternative is to disconnect
the horns, then operate the horn switch. A clicking sound from the vehicle will confirm the
presence of a horn relay. Another alternative is to check a wiring schematic of the vehicle
in question.
Configuring An Optional Relay:
The Brown Siren / Horn output wire has a 1 Amp
capacity, which, if exceeded, can damage the security system control module. In certain
situations, among them multiple optional sirens or utilizing the vehicle's horn, an optional
SPDT relay is required. When adding a relay, a protection circuit in the form of a 1 Amp
diode on the Brown Siren / Horn output wire is recommended.

3 Wire Positive Pulse Systems:
This power doorlock system is very similar
to the three wire negative pulse system except the vehicle's doorlock switches use 12 volt
positive pulses to operate the vehicle's doorlock relays or control unit. Examine the wires
on the back of the switch. Of the three wires, one will be constant 12 volt positive, regardless
of the switch's position. Of the two remaining wires, one will show 12 volt positive when
the switch is pushed to "lock", and the other will show 12 volt positive when the switch is
