4.9 Connect the MVP "Transmit Lockout Input" pin to the Transmit Key:
Pulling the MVP Transmit Lockout Input pin to ground freezes the displayed values for the various functions.
This eliminates jumpy readings during transmit. In most (if not all) cases the MVP “Transmit Lockout Input"
does not need to be connected. If transmit lockout is required, attach the appropriate pin (see the “Working
with Connectors” section of this manual for more information) to a 20 ga. wire. Install the wire with pin into
position 3 of the MVP connector. Route and attach this wire to the transmit key.
4.10 Connect the MVP Harness to Power and Ground:
Route the power wire (red) to the main bus via a 5-amp Circuit Breaker. Route the ground wire (black) to the
aircraft ground.
WARNING: The power wire is RED and is connected to pin 1 and 2 on the MVP. If aircraft power is con-
nected to any pin on the MVP other than pin 1 and 2, damage to the MVP and any connected hardware may
occur. Insure power is provided on pin 1 and 2 of the MVP before attaching the connector.

4.11 Connect the MVP Harness to the CO-Guardian CO Detector:
If a CO detector was installed, connect the RS232 output from the Remote Mounted 353-201 (experimental
only) or 452-201-011 (certified) CO Detector to Pin 11 (Port 3 In) on the MVP. Refer to CO-Guardian’s
installation instructions for further information on the CO Detector.
Note: The CO Detector share the same port on the MVP as the second EDC. If the CO Detector is installed a
second EDC cannot be installed.
