Connecting the electrical power to MagicSpeed
Twisted cable pair (blue and blue/white)
I
NOTE
 Both these cables are only connected when there is a CAN
bus connection.
They are not required for analogue connection. In this case,
insulate the ends and store them.
 Do not mix up the cables. Otherwise the cruise control will not
function.
➤ Connect the blue cable (P3) to CAN high.
➤ Connect the blue/white cable (P2) to CAN low.
I
NOTE
For a CAN bus connection, all cables in the cable set are now con-
nected. You can now install the control element, see chapter
"Installing the control element (accessory)" on page 62.
In this case, insulate the ends of the remaining four cables and
store them.
Brown and brown/white
I
NOTE
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.
