IMPORTANT! After reading this manual, start the installation by affixing
the WARNING DECAL to a readily visible area in the engine compartment!
Installation Considerations: This entire booklet should be read before starting the
installation. An understanding of which control module wires are to be used and their
functions is essential. Installations will vary from car to car , as some control module wires
are required, while others are optional. Before starting the installation, it should be deter-
mined which control module wires will be used. Most installers will list these wires, then
"map out" the installation by locating and noting the target wires in the vehicle. This will
also determine the best location for the RS-4LX control module, which is mounted upon
completion of the installation.
The RS-4LX duplicates, with on-board control circuitry and relays, the actions that
occur within the ignition switch when you use your car's key to start the engine. Because
of this, most of the main wiring harness connections will be made at the ignition switch
harness. This will be located around the steering column area. Caution! Avoid the Airbag
circuit! Especially avoid any harness or wires encased in Yellow or Red tubing or sleeves.
Do not use a standard test light, as it can deploy an airbag or damage on-board computers
and sensors if the wrong circuits are probed.
The ignition switch wires usually are high amperage circuits, which means that high
reliability connections must be made! We recommend proper soldering of all connec-
tions. Some installers connect a battery charger to the vehicle's battery during the installa-
tion to prevent battery drain. While this is a good practice, the battery charger must be
removed before attempting to use the RS-4LX to start the engine.

Accessory in "Run". The two circuits needed for the climate control system, HVAC Con-
trols and Blower Motor, require considerable current as indicated by their much higher
fuse rating.
Upon remote starting, since both Ignition #1 and Ignition #2 must be powered for the
engine to run, the RS-4LX's Blue and Yellow Ignition wires will be utilized to accomplish
this. However, two additional circuits are required to power the HVAC system, and Park-
ing Light operation is also desired. In this situation, the RS-4LX's White Accessory wire
will be used to trigger three additional optional SPDT relays. The three optional SPDT
relays that will be added to this installation will all be configured the same way. We
recommend also using an optional AU-SOCKET-5 with each relay to save time and sim-
plify the installation. Use the diagrams on this and the following pages to configure the
added relays.
