Congratulations for choosing the Modular Advanced Remote Starter and Keyless Entry
system. The MARS-22
offers the convenience of locking and unlocking your vehicle’s
doors with the press of a button, and starting your vehicle's engine from the comfort of your
home or office, allowing it to warm up in winter and cool down in summer. The MARS can
also be configured to remotely open your vehicle’s trunk.
It is highly recommended that this system be professionally installed, as the sophistica-
tion of the modern automobile and the complexity of this type of product installation is often
beyond the abilities of most do-it-yourselfers.
There are several important safety considerations with using and installing the MARS
keyless entry and remote starter. Among them are:
✓
This unit is for vehicles with an automatic transmission only. Installation in a
vehicle equipped with a manual transmission can result in property damage or
personal injury.
✓
This unit is for fuel injected gasoline or diesel engines.
✓
Children should not be left unattended in, or be allowed to play with the activat-
ing transmitters of any remote starter equipped vehicle.
✓
Do not use the remote starter feature in an enclosed garage or other structure.
Introduction & Safety Considerations

The MARS is a very flexible system. It has capabilities, such as sounding the horn, which
may or may not be utilized in your installation. It also has many programmable features
which can affect its operation. While these are explained as thoroughly as possible in this
guide, your Omega dealer or installer is the best source for information about your system.
This power doorlock system differs from the negative and positive pulse systems in that there
is no doorlock control unit or relays. In this type of system, the switches themselves supply the
positive voltage directly to the doorlock actuators, and, more importantly, provide the return
ground path. It is important to note that the lock and unlock wires in this system
actually rest
at chassis ground. This means that both the lock and unlock wires must be "opened", or cut,
to make the proper connections.
Examine the wires on the back of the switch. (Normally 5 wires will be found
1) One wire will show +12 Volts, regardless of the switch's position.
2) Two wires will be grounded regardless of the switch's position.
3) One wire will show +12 Volts only when the switch is pushed to "Lock".
4) One wire will show +12 Volts only when the switch is pushed to "Unlock".
- When the lock /unlock wires are found, they must be cut one at a time. If the correct wires
are cut the door locking system should not operate from the primary switch.
- Notice that in the diagram the driver's switch is the primary or “Master” switch (in some
vehicles, the primary switch is on the passenger's side). The half of the cut wires which come
from this primary switch are referred to as the "Switch" side. The half of the cut wires which
go to the secondary switch are referred to as the "Motor" side even though the cut is made
between the switches.
the wires
show partial ground through the relay’s coils.
2) The doorlock switch in a Reversing system will have 5 wires, while a Positive
pulse system the switch will have 3 wires.
3) A
Positive pulse system uses factory relays or a control unit, a Reversing system does
not.
