Step 2. +12V P
NOTE: Thinking ahead...In Step 5, you will bring the sensor leads, +12V wire, and ground wire to
a single point of your choice under the dash and connect them to the display harness cable.
Choose this single point now. The sensor leads must be led into the vehicle cabin. Usually
you can use an existing feedthru in the firewall. If your fusebox is in the engine compart-
ment then you may also need a feedthru to bring the +12V and ground wires through into
the vehicle cabin.
The DriveRight requires an unswitched +12V connection to your vehicle and a
ground connection to the vehicle chassis. These connections are often most easily
made at your vehicle's fusebox. A direct connection in your fusebox is best - some
vehicles have extra slots for accessories such as the DriveRight. You may need to buy
the proper termination for use with your vehicle's fusebox - consult your dealer or
local auto parts store. Attach the termination or connector to the end of the red
+12V wire with fuseholder (16) and insert into your fusebox. Otherwise select an
unswitched wire exiting the fusebox that does not involve safety-related equip-
ment such as headlights, brakes and so on. Possible candidate wires may include
the wires used for the cigarette lighter, dome light (before the switch), glove com-
partment light, clock, tail gate light and other convenience functions. The wire
used should be 22-18AWG or have the same diameter as the red +12V wire with
fuseholder. Use the in-line splice (20) to make the connection to the red +12V wire
with fuseholder (Figure 9). Trim off flush the stripped portion of the red wire. The
fuseholder should be in the vehicle cabin.
