MagicSpeed MS880
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.
Yellow and blue
I
NOTE
Both these cables are only connected when there is an analogue
connection.
They are not required for the CAN bus connection. In this case,
insulate the ends and store them.
The yellow cable and the blue cable are for connection to the travel speed
and engine speed signals respectively:
 Blue:
Records the engine or travel speed signal with a voltage between 1.5 V
and 24 V and a frequency between 6 Hz and 8.5 kHz.
Use the blue cable for speed signals whose voltage and frequency are
within above-mentioned ranges.
 Yellow:
Records the engine speed signals with a voltage between 6 V and 250 V
and a frequency between 6 Hz and 488 Hz.
Use the yellow cable to record engine speed signals with a voltage of
more than 20 V or when engine overspeed protection is required.

NOTE
The signal input depends on the vehicle's transmission.
