Extra features

Two auxiliary channels allow you to add functions like turning on the dome light and defroster. The system is compatible with most factory and aftermarket security systems. The RS-370 module uses Excalibur's Vehicle Learn Technology to automatically detect the vehicle's ignition, accessory, and start sequence, and then reconfigure itself to match. Loading and downloading programming is not necessary.


In most applications the RS-370 remote start system requires a digital immobilizer bypass module, like the Omegalink OL-MDB-ALL, for full remote start functionality.

If you know how to use a multimeter and have experience working with your vehicle's electrical system, you should be able to install this remote start system yourself. If not, please consider having your system professionally installed.

To ensure vehicle compatibility, please enter your vehicle information. Your order will be reviewed by our Car Experts group, who will contact you if further information or recommended accessories are needed.

Product Research


Overview: The Excalibur (Omega) RS-370 is a remote start & security system designed to be installed on most any vehicle and provide state-of-the-art vehicle security and convenience features. The RS-370 lets you control your vehicle from up to 1500' away, while built-in remote start capability will keep your vehicle warm in the winter and cool in the summer.

Note: This is a complex product; it is recommended that the installation be performed by a professional installer or experienced do-it-yourselfer.

Vehicle Learn: The RS-370 features Omega's Vehicle Learn procedure that, in a few easy steps, will quickly configure the most install-critical features to match the vehicle requirements. Vehicle Learn options include:

  • Automatically configures Ignition, Accessory, and Start circuits to match the vehicle.
  • Let you choose crank delay.
  • Sample crank time for crank averaging (tachless modes only).
  • Auto-detect engine running method - Data-tach, tach wire (will also tach learn), or tachless mode.
  • Auto-detect data port protocols.
  • Lets you quickly enable manual transmission reservation mode.

Immobilizer Bypass: The RS-370 does not include an immobilizer bypass circuit or module, which most modern vehicles will require, and must be purchased separately. The remote start system is compatible with most immobilizer bypass interfaces, such as the Omegalink OL-MDB-ALL data integration module (sold separately), supporting both DBI and iDatalink protocols.

Remote Controls: The RS-370 includes two 4-button remote controls, both 1-way, for operating the remote start system with up to 1500' of operational range. Both remotes let you activate up to 13 functions and feature an Excalibur logo LED that lights when any button is pressed. The included remote controls come pre-programmed to operate out of the box, but replacement or additional remotes can easily be programmed to work with the system.

  • Remote Functions: Both remotes can be used to activate the following functions: Remote Start, Arm/Lock, Disarm/Unlock, Trunk Release, Silent Arm/Disarm, Sensor Bypass, Low Voltage & High/Low Temperature Auto Start, Panic, Remote Valet, and activation of up to 4 Auxiliary Functions (vehicle dependent).
  • Auxiliary Functions 1-4: Up to 4 Auxiliary Functions are provided, which are designed to operate extra vehicle functions like automatic sliding doors, or a motorized sunroof. These are "virtual" outputs, with no physical wiring provided, with functions determined when the system is integrated into the vehicle's data network during the Vehicle Learn procedure. After Vehicle Learn, each Auxiliary Function can be triggered to determine which vehicle function, if any, is assigned.

Included Harnesses: The RS-370 includes 4 harnesses for interfacing the vehicle's wiring:

  • 6-Pin High Current: Includes wiring for remote starting the vehicle such as Ignition, Start, and Accessory.
  • 3-Pin Remote Start: Includes remote start Status outputs.
  • 3-Pin Door Lock/Unlock: Provides lock and unlock output wires, each with a 250ma ground (-) output.

    Note: When interfacing with any other type of factory door lock system besides negative switching locks, or when adding aftermarket actuators, two relays (such as two 120E5000s) or a door lock interface module (607451M) will be required. If your vehicle requires the use of a Data Integration module that controls your factory door locks, no extra parts besides the Data Integration module will be required.

  • 14-Pin Main Input/Output: Includes wiring for key features such as: Starter Interrupt output (-), Parking Light flash (10A, fused), Trunk Release (-), Hood Pin Switch trigger, Horn Honk/Siren output (-), and more.

    Note: Siren and Starter Interrupt relay sold separately.

Antenna/LED/Valet: The Excalibur system includes a transmitting antenna for mounting in the dash or to a window. The Antenna also houses the Status LED and the Valet button for programming.

Note: The Antenna should be mounted up high on glass or other solid surface for best transmission/reception as well as shock sensitivity. This also allows the security LED to be seen.

Data/Telematics Ports: The RS-370 includes 2 Data Ports (black & green) that can be used for an immobilizer bypass, shock sensor, or telematics module (all sold separately).

Temperature Sensor: The RS-370 includes a Temperature Sensor on the top panel that can be used for high/low temperature auto start and for automatic low temperature crank extender.

Programmable Options: The Excalibur remote start and security system includes 20 Programmable Features that can be custom configured for your application. A handy programmable feature chart lets you see at a glance what features and options are available, with the default settings highlighted. 

Turbo Timer Mode: This mode allows turbocharged vehicles to continue running for a programmable amount of time (1, 2, or 3 minutes) after driving, allowing the engine and turbo to cool properly before shutting down.

Pit-Stop/XL Pit-Stop Modes: Pit-Stop mode can be activated, allowing you to turn the key off, but let the engine continue to run for the programmed amount of Run-Time - 3, 10 (default), 15, 20, or 30 mins. XL Pit-Stop mode will keep the vehicle running for 12 hours and can be extended up to 24 hours. This is ideal for commercial work vehicles that need to remain running, such as refrigeration trucks, cleaning vans, vehicles with power take-offs, etc.

Low Voltage & High/Low Temp Automatic Starting: This feature will automatically start the engine if the vehicle battery drops below 11.5V or the interior temperature goes above or below the programmed threshold.

Manual Transmission Starting: Even though the RS-370 can be configured for remote starting a vehicle with a manual transmission, we do not recommend this option for safety reasons. Crutchfield cannot provide Tech Support for any installations in vehicles with a manual transmission.

Anti-Carjacking Protection: The RS-370 includes 2 separate Anti-Carjacking features that can trigger the system into alarm mode, sounding the horn or siren and flashing the parking lights. Within 53 seconds of activation, the system will chirp until going into full alarm mode at 60 seconds, unless properly deactivated. Either or both of these methods can be activated and is user-selectable in the Programmable Features menu. The 2 different types of Anti-Carjacking protection include:

  • Ignition Activated: This activates every time the ignition is turned on, and requires the Valet Switch to be pressed within 60 seconds to deactivate.
  • Door Activated: When a door is opened while the vehicle is running, the Valet Switch must be pressed within 60 seconds to deactivate the Anti-Carjacking.

Last Door Arming: The RS-370 can be configured to automatically arm when all the vehicle's doors are closed. Arming starts 30 seconds after the last door is closed.

Automatic Re-Arm: This feature, when configured, allows the system to automatically re-arm 90 seconds after being disarmed by the remote if no door is opened during that time.

Alarm&Remote Start Diagnostics:

  • Alarm: A Quick Test mode lets you test all zones of the alarm system and quickly adjust any sensors. Zone Violation Recall can show you what zone triggered the system by producing a series of flashes on the Status LED that correspond to that zone. Zones include Sensor Warning (pre-warn), Sensor Trigger, Hood, and Door.
  • Remote Start: If the remote start system fails to properly start or stay running, it can indicate which zone caused it to shut down. After shutdown, putting the system in valet mode will cause the status LED to flash a certain number of times, indicating one of the following problems:
    • Hood was opened.
    • Brake pedal was pressed.
    • Bad tach signal or engine overrev.
    •  Neutral safety circuit was triggered.
    • The 3D sensor (antenna) detected vehicle motion.
    • The system received a command to stop.
    • The alarm was triggered.
    • Run time has expired.
    • Low battery voltage was detected.
