Installation Precautions - Rosen M10 Monitor/ Dual-Zone Controller Installation Manual

4 Route the harnesses and make all wiring connections
Basic connections are described in this section. Also see wiring diagrams starting on p.19.

INSTALLATION PRECAUTIONS

• Use caution to assure that harnesses and cables are protected from sharp
edges. Where necessary, add tape to cover sharp surfaces.
• Avoid sharp bends (always less than 90
• The locking connectors in this system require that even force be applied to the
release latch when harnesses are disconnected. Failure to use reasonable care
will damage the connector and cause system failure.
CABLE AND HARNESS ROUTING
1 Starting at the headliner cutout, route the black power harness to the underdash area.
Leave about six inches of cable hanging through the cutout. Allow enough slack in the
harnesses above the headliner to allow working room. You may want to leave a short
loop hanging out the side of the headliner until final re-assembly (this makes stuffing
cables into the headliner easier when you mount the unit).
2 You may want to secure the cables with tape so they lie flat. This makes it easier to
reassemble the vehicle trim correctly, especially with sunroof vehicles.
3 If any other optional harnesses are being used, route them from the headliner cutout to
their destination. Remember to leave working slack.
When using optional harnesses, you may need to split the harness paths, routing
some harnesses down one side of the vehicle and the rest down the other.
CONNECTING THE POWER HARNESS
The system requires both constant 12V (+) and switched 12V (+) energized when the key is
in the Accessory position. These can be found at the ignition switch harness. The ground
wire should mount to bare metal, using a factory ground bolt whenever possible.
Power Harness Connections:
Yellow 12V (+) Constant Battery Power (Fused 7.5 A)
Red 12V(+) Switched Accessory (Fused 1 A)
Black Chassis (-) Ground
Orange Vehicle Illumination Input (12V(+) when the parking lights are on)
IMPORTANT:
- Connecting the Red wire to constant 12V(+) causes battery drain
!
and premature battery failure.
