Negative chassis ground. If the horn sounds when probed in this manner, a direct
connection may be made.
Once the vehicle's horn wire is identified and confirmed to draw (-) Negative 250mA or less,
the Pink wire may be directly connected to the vehicle horn wire. If the presence of a factory-
equipped horn relay cannot be confirmed, use the following diagram for “Driving a Relay”.
CAUTION! Avoid the airbag circuit! Improper use of a test light can
cause deployment of the airbag, which may result in bodily injury! Test
lights can also damage on-board computers and associated sensors.
CONNECTION:
The
Driving a Relay
connec-
tion of the Pink wire is used
when the vehicle does not
have an existing horn relay
only, or the vehicle’s horn
circuit is (+), or otherwise
draws more than (-) Nega-
tive 250mA. This diagram
shows how to configure the
optional standard automo-
tive relay.
The
Brown wire
is a 1 amp Positive 12 Volt output which sounds an optional electronic
siren as part of the system's audible output. Besides the polarity difference, unlike the Pink
wire, the Brown wire has a steady output during a system activation.

The Type 4 Connection:
This system is used to interface the AL-100-H with many Ford,
Lincoln and Mercury vehicles. In this type of Remote Keyless Entry system, all of the doorlock
relays are built into the RKE module, a back feed pulse is generated by the module and the
doorlock switches generate Negative pulses instead of Positive,
preventing using the Green and Blue pass through wires.
The diode is needed
to block the
negative pulse
generated by the
Remote Keyless
Entry unit so that
the AL-100-H can
only detect the
negative pulse
from the switches.
Connections are
made easiest at
the RKE module
itself.
