with a water tight plug on the end. There is also a heaver wire Extension
Cable (G) 10 feet in length. This will allow you to use up to 15 feet of wire
for the installation from the magnetic sensor location to the terminal block.
Depending on where you have attached the magnetic sensor (Front Wheel
CV Joint or Rear Wheel Drive Shaft) and the location of the terminal block,
you may or may not need the extension cable.
If the extension cable is needed, plug the extension cable into the magnetic
sensor cable using the water tight connector, then cut the extension cable
to the required length, strip back the insulation on the Red, White & Black
wires and attach to the terminal block as shown in Figure 2-17. Each wire
should be connected to a separate terminal on the block.
If the extension cable is not needed, cut the plug off the end of the smaller
magnetic sensor cable, strip the wires and attach to the terminal block as
shown in Figure 2-17.
Once the magnetic sensor has been properly connected to the terminal
block, connect the terminal block to the vehicle’s battery using the black
and red cables provided.
The RED wire with the in-line fuse (+12VDC) should be connected to the
POSITIVE terminal on the battery and to the same location on the terminal
block as the red wire from the magnetic sensor. The BLACK wire (Ground)
should be connected to the NEGATIVE terminal on the battery and to the
same location on the terminal block as the black wire from the magnetic
sensor.
Finally, connect the DMI Connector Cable (K) to the terminal block as
follows:
• Connect the black wire to the battery ground and sensor black wire.
• Connect the yellow wire to the battery +12 VDC and sensor white wire.
• Connect the green wire to sensor red wire.
The red wire from the DMI connector cable is not used.
Once these steps are complete, you may connect the RAC itself.
