Connecting the electrical power to MagicSpeed
Brown and brown/white
NOTE
I
Both these cables must only be connected when there is an ana-
logue connection.
They are not required for the CAN bus connection. In this case,
insulate the ends and store them.
Connect the brown cable and the brown/white cable to the brake light
switch (fig. 9 1, page 7).
If there are more than two cables leading from the brake light switch, this is
how to identify the two cables you need:
Use a voltmeter to measure the voltage on the cables.
One of the two original cables on the brake light switch should have a
permanent positive voltage (terminal 30, 12 V) or a connected positive
voltage (terminal 15).
The second original cable should have a voltage of +12 V when the
brake is applied. As soon as the brake pedal is released, no more volt-
age should be on that cable.
If you cannot measure a full +12 V on the brake light switch, you vehicle prob-
ably has a digital brake system.
In this case, connect the two cables as follows:
Connect the brown/white cable to a fuse-protected, connected positive
terminal (terminal 15).
Connect the brown cable to the original cable leading to the brake lights.
The voltage on this cable is +12 V with the brake applied, and 0 V with
the brake released. You will find these cables directly at the rear lights or
in the wiring harness at the rear of the vehicle.
