Electrical connections, Fig. 2
☞
Route all wiring with care. For wiring details, refer to the connection diagram on the back
cover page and to the following table.
☞
Do not cut non-assigned wires. Instead, wind them together and secure to one side. They
may be required for retrofitting additional functions.
Power supply cable
Wire colour
Connection
Yellow
+ 12 V permanent positive (must be rated for at least 4 A.)
Red
+ 12 V ACC / ignition positive (without switch-off on starting engine)
Black
Battery negative (body)
Blue/white
+ 12 V remote input AV1 (activates the audio / video input 1)
Blue/yellow
+ 12 V remote input AV2 (activates the audio / video input 2)
Green
+ 12 V reversing signal (reversing light positive), active at + 12 V (active high)
Grey
+ 12 V parking brake signal, active at earth potential (active low)
A
Only connect electrical signals to suitable connecting points in the vehicle.

For direct connection of permanent positive (yellow lead) to the battery, the fuse must be no
further than 10 - 15 cm from the positive terminal of the battery. If it is necessary to extend the
positive lead, an additional 10 A fuse must be provided close to the battery (max. distance 10 -
15 cm). Failure to do so may result in a wiring fire hazard.
■
12 V permanent positive (yellow):
☞
Connect yellow wire to a suitable connector with 12 V permanent positive.
A
This connection should be rated for a current of at least 4 amps.
■
12 V ignition / ACC / accessory contact (red):
☞
Connect red wire to a suitable 12 V circuit switched through the ACC ignition key contact.
■
Battery negative (black)
☞
Connect black wire to a suitable earthing point on the vehicle body.
■
12 V remote inputs AV1 and AV2
In order to ensure full functionality of the MI 2200, the external video sources should be
provided with a 12 V remote control output.
a) Remote input AV1 (blue/white):
☞
Connect blue/white wire to 12 V remote control output of the video source to be
connected to the AV1 input of the MI 2200.
b) Remote input AV2 (blue/yellow):
Connect blue/yellow wire to 12 V remote control output of the video source to be connected
to the AV2 input of the MI 2200.
■
Reversing signal (green)
☞
Connect green wire to a suitable reversing signal point (positive lead of reversing light).
■
Parking brake signal (grey)
☞
Connect grey wire to a suitable parking brake signal point.
If the MI 2200 is used with both monitors for the rear passengers, the grey wire should be
permanently connected to earth.
