Some vehicles have a single Constant 12 Volt circuit supplying the ignition switch. A
schematic of the car's electrical system will show if this is the case. If so, the Red wire may
be connected at the ignition switch wiring harness, but the fuse holder and 30 amp fuse
must also be used.
The use of the 30 amp fuse and the fuse holder is required! Failure to
properly install the fuse holder and the 30 amp fuse will void all warranties.
Blue Wire: Connection Required
This wire must be connected to the vehicle's Ignition #1 (also known as Primary Igni-
tion) wire. This wire will measure Positive 12 Volts when the ignition key is in the "Run"
and "Start" positions and no voltage in the "Off" and Accessory positions. This wire is
found in the ignition switch wiring harness. If two Primary Ignition wires are present, the
Yellow wire may be used on the second wire. If more than two Primary Ignition wires are
present, you will also need an optional prewired dual relay socket and relays.
Green Wire: Connection Required
Connect this Green wire to the vehicle's Starter wire. This wire will show Positive 12
volts when the ignition key is in the "Start" position only. This wire is also found in the
ignition switch wiring harness. Some vehicles have a second Starter wire known as a
"Cold Start" wire. When this is encountered, if the two Starter wires are the same circuit
you may connect both of these wires to the Green wire. If the two Starter wires are

Installing an RS-4LX to this type of ignition switch is a strait-forward procedure,
involving no additional relays or other parts, as shown by this diagram after installation.

Basic Ignition Switch Schematic After Installing The RS-4LX:
As automotive electrical systems increased in complexity, so have ignition switches.
Many newer vehicles utilize a complex ignition switch to accommodate the increased cir-
cuitry. This type of ignition switch requires additional parts and installation consider-
ations.
