The MARS Programmable Features are arranged so that the “operational” features, which
are of user interest, come before the “installation”-related features. The purpose of instal-
lation-related features is to adapt the MARS to certain vehicle situations; these are to uti-
lized at the time of the installation only.

tures to their factory settings. This is extremely helpful if there has been a mistake in
programming, or if there is any doubt or confusion of the settings.
5) Select another feature by again making a new entry of Valet Switch presses
(repeating step 3) and again setting the newly chosen feature with the transmitter (as in
step 4).
Exiting Programming Mode:
Simply allow the MARS to time out of Features Programming Mode by not performing
any programming actions for 15 seconds; or, turn the ignition “On” to exit immediately.
The MARS indicates its exit from Features Programming Mode with 2 short and 1
long Status Lights flashes and the parking lights turning off. If the horn is con-
nected it will have 2 short and 1 long chirps.
About the Programmable Features
braces are not adequate, and the area must be clean, bright metal.
20-Gauge Red/Black Wire:
( + ) Brake Input
Connection Required-
The Red/Black wire must be connected. It is part a critical
safety feature which disables the unit whenever the brake pedal is pressed. Connect the
Red/Black wire to the brake switch wire which shows +12 Volts when the brake pedal is
pressed. The brake switch is typically located above the brake pedal, and usually mounted
to the brake pedal support bracket. Make this connection securely for long-term reliability,
and thoroughly test the operation of this circuit.
The Hood Safety Switch must be installed and the Blue
wire must be connected. This prevents operation of the unit if the hood is open. Carefully
install the included pin switch so that it is open (pin down) when the hood is shut and closed
(pin up) when the hood is open. Connect the Blue wire to the pin switch and carefully route
this wire through the firewall, using an added or existing grommet, avoiding any hot or
moving parts. If there is an existing hood pin switch for an alarm system, you may use it for
this purpose, but the two systems must be diode-isolated. Instead of using a pin switch to
monitor the hood's open or shut status, an Omega AU-46 Mercury Tilt Switch may used.
Connect one of the AU-46's wires to Negative Chassis Ground and connect the remaining
wire to the Blue wire.
20-Gauge Blue Wire:
( - ) Hood Input
Connection Required-
20-Gauge Black/Yellow Wire:
Engine Detect Input
Connection If Desired.
The Black/Yellow wire is the engine detect wire. The MARS
unit utilizes two different methods of monitoring the vehicle during the remote starting pro-
