The next step is to connect the P o wer, Ground, and Remote wires to your X3.The po w er
wire should run from the mounting location through the vehicle to the battery or power
distribution block.install a fuseholder at the power end of this cable within 18 inches of the
power source.Avoid sharp corners, creases, and sharp body parts.When passing through
any metal wall (i.e.firewall etc.), a grommet must be used to prevent the wire from chafing
and shorting to ground.
The ground wire should be of the same gauge as the power wire.As a rule of thumb, use
as short a length of wire as possible.
Find a location near the X3 that is
metal (the floor pan is normally a good
location) and clean an area about the a
half inch in diameter to bare metal.Drill a
pilot hole in the middle of this area.
Be Careful! Inspect the area underneath
to be sure you are not drilling into wires,
brake or fuel lines, etc. Terminate the
wire with a ring connector and attach it to
the bare metal using a #8 sheet metal
screw and washer (not supplied). We
suggest crimping and/or soldering this
connection. After the connection is
complete, coat the area with silicone or
some similar material to prevent rust
from developing.
Connect the remote wire to the amp
remote wire of the head unit, or to the power antenna wire if the head unit does not have
a separate amp remote wire.This wire supplies a 12 volt signal to the X3 when the main
system is activated.
Once you have routed the po wer, ground, and remote wires through the vehicle, it is time
to connect the wires to the X3. Be sure that you have not reconnected the ground cable to
the negative post of the battery.
Cut off excess wire and, using wire strippers, strip the power, ground and remote cables
about 1/8 inch. Locate the power, ground, and remote Powerlock connector (supplied). On
the top of the connector are three slotted screws. With a small flat-bladed screwdriver,
loosen the screws before attempting to insert the cables. After you have inserted the
stripped end of each cable into the connector, secure it b y tightening the associated scre w.
Check that each connection is tight.If the wires are secure, the connector may be plugged
into the X3.
