Omega AL-100-H Installation Instructions Manual page 10

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.

connection may be made.
CAUTION! Avoid the airbag circuit! Improper use of a test light can
cause deployment of the airbag, which may result in bodily injury! Test
Pass.
lights can also damage on-board computers and associated sensors.

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".

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.
