Note: Correct electrical polarity is required for safe and proper installation. The cradle will not power on or function if the
cable is connected with the polarity reversed. See the following figure titled “Vehicle Connection Wiring Color Codes”
for additional wire color-coding specifics.
How To: Connect Vehicle 12 VDC Connection
1. The power cable must be UNPLUGGED from the MX7 Tecton vehicle cradle.
2. While observing the fuse requirements specified above, connect the power cable as close as possible to the actual
battery terminals of the vehicle. When available, always connect to unswitched terminals in the vehicle fuse panel, after
providing proper fusing.
ATTENTION: For uninterrupted power, electrical supply connections should not be made at any
point after the ignition switch of the vehicle.
3. Route the power cable the shortest way possible. The cable is rated for a maximum temperature of 105°C (221°F).
When routing this cable it should be protected from physical damage and from surfaces that might exceed this
temperature. Do not expose the cable to chemicals or oil that may cause the wiring insulation to deteriorate.
Always route the cable so that it does not interfere with safe operation and maintenance of the vehicle.
Use proper electrical and mechanical fastening means for terminating the cable. Properly sized “crimp” type
electrical terminals are an accepted method of termination. Select electrical connectors sized for use with
18AWG (1mm2) conductors.
