ISO plug / socket pin assignment
Port A (power supply)
On the A side you can find the port for
power supply.
A1 – (-) hand brake (brown)
A2 – spare
A3 – (+) 12Volt reverse light (pink)
A4 - (+) 12Volt battery* (yellow)
A5 – (+) electric antenna (blue)
A6 – spare
A7 - (+) 12Volt ignition plus* (red)
A8 – (-) minus / ground (black)
* Some vehicle manufacturers use their
own pin assignment. Especially the
terminals A7 (ignition plus) and A4 (steady
plus) are often interchanged. The incorrect
connection in this case leads to following
problem: the unit can not be turned on if
the ignition is off and all the saved settings
are lost as soon as the unit will be turned
off. If these problems appear the connec-
tions A4 and A7 should be interchanged.

Though the design of ISO port is
standardized, it's pin assigment is not
and may vary. Thus in case of mismatch
of connections due to different pin assig-
nments a simple plug'n'play connection
may lead to grievous errors.
