engines, operates only if programmed (feature
nect the Green/Red wire to the wire in the vehicle which powers the glow plugs, or the wire
which illuminates the "Wait To Start" light on the instrument panel. When connected, the
unit will not engage the starter if the Green/Red wire has +12 Volts; in other words, using
this wire simply delays the unit's engagement of the starter. If the "Wait To Start" light in the
vehicle has a Negative switching circuit, change the position of the White "Glow Plug +/-
Select" Jumper on the control module to reverse the Green/Red wire's polarity operation.
20-Gauge Yellow/Green Wire:
Connection If Needed.
If needed, the Yellow/Green wire allows the MARS to disarm a
factory alarm system. Connect the Yellow/Green wire to the wire in the vehicle which is
connected to one of the doorlock key cylinders. The typical OEM alarm has an electrical
switch in the key cylinders which switches -Ground when the key unlocks the door. This

How to program the features:
1) Turn the ignition key "On", then "Off".
2) Within 7 seconds press the Valet Switch 5 times.
The Status Lights will flash twice, and if the horn is connected, it chirps twice.
The parking lights turn on, and stay on while in programming mode.
3) Select the feature to be changed by pressing the Valet Switch the same number of times
as the feature number (example: feature
The Status Lights will flash the same number as the Valet Switch presses just
entered. If the horn is connected, it also chirps the same number.
Count the number of flashes or chirps to confirm that the desired feature has been
chosen (if needed, reenter the Valet Switch presses).
4) Once the feature has been confirmed, press the transmitter buttons as follows:
"LOCK" = Feature's Default 1st setting ( 1 Status Light flash & 1 horn chirp )
"UNLOCK" = Feature's optional 2nd setting ( 2 Status Light flashes & 2 horn chirps )
• Most of the programmable features offer more than one optional choice:
"START" = Feature's 3rd setting ( 3 Status Light flashes & 3 horn chirps )
"TRUNK" = Feature's 4th setting ( 4 Status Light flashes & 4 horn chirps )
Once the Status Lights flash a response, and the horn chirps the response
(if connected), the feature is set.
