The MARS has a total of 14 “programmable features”; most of these are “operational”
features, some are “installation”-related, and one returns all features to the factory setting.
These features can be changed by very easily by placing the MARS into a “Features Pro-
gramming Mode” and selecting features with the Valet Switch, and then using the
transmitter’s buttons to set the feature as desired. The chart on the next page shows the
Programmable Features, and detailed step-by-step programming instructions follow the
chart.
Programming Features

The Receiver Unit is designed for mounting di-
rectly on the vehicles’ window glass, which also
gives the system its best operating range. Should
this not be possible or desired, the Receiver Unit
may be mounted in a hidden location, and provi-
sions are made for optional separately-mountable
Valet Switch and Status Light.

An important part of the MARS system is its Receiver Unit. As its name implies,
the Receiver Unit contains the radio receiver needed for the system to operate
from the hand-held transmitter. The Receiver Unit also contains the Valet Switch
and Status Light; the various operations of which are explained throughout this
guide. The Status Light also briefly flashes the number of transmitters able to
operate the system every time that the ignition key is turned on.
wire can usually be located in the vehicle in either kick panel area, in the wiring
harness which is routed into the cab from the door. The Yellow/Green wire has a
-Ground pulse whenever the MARS has an unlock output or its remote start operation is
activated.
20-Gauge Yellow/Red Wire:
( - ) OEM Arm Output
Connection If Needed.
This output may be used to arm a factory-installed alarm, or, if
the vehicle is equipped with a Retained Accessory Power circuit, this output can be used to
“spike” the door pin switch wire, which will turn off the Retained Accessory Power circuit.
To arm a factory alarm after remote start engine run stops, connect the Yellow/Red wire
to the vehicle's factory arm wire. This wire will show Negative polarity when a key is held in
the "lock" position in the door key cylinder. This wire can usually be located in either kick
panel, in the wiring harness from the door, as it is routed between the door key cylinder and
the factory alarm.
To use this wire to turn off Retained Accessory Power, locate a vehicle wire within the
door or doorjamb which shows Negative when the door is open. Should such a wire be
found which is positive, a relay is needed to reverse the Yellow/Red wire’s Negative output
to Positive. The Yellow/Red wire produces a Negative pulse output whenever the system
turns off the engine after it has been remotely started.
20-Gauge Pink/Black Wire:
( - ) Start Activation Input
Connection If Needed.
The Pink/Black wire allows for alternative devices such as an
existing keyless entry or alarm system to activate the remote start operation. If the Pink/
Black wire receives a Negative pulse, the MARS unit will start the vehicle's engine, pro-
vided that all safety circuits are in the proper status. After the engine has been started by
remote control, another Negative pulse on the Pink wire will turn the unit off, stopping
