We folded any excess wire and neatly stored
it just above the ABS system. Even though
nobody would see our work once the tank
was in place, we believe neatness counts
and helps to insure that the entire wiring
process is done correctly.

The harness has two separate power leads
that go the lights. We ran a lead along each
side of the frame to an IPF light. We zip-tied
the lead to the LightBar and frame tubes.
We ran the power switch to the left handlebar
and mounted it above the high beam switch,
using the supplied adhesive pad. We zip-tied
the wire to the handlebar at 4” intervals.
We then ran the wiring harness back toward
the battery where we connected the main
power lead to one circuit of a Centec fuse
panel. We eliminated the in-line, 25-amp
fuse supplied by IPF, and relied on the
Centec fuse panel to protect the wiring circuit.
The YELLOW wire on the IPF wiring harness
is the relay command circuit.
We picked up power for our command circuit
by tapping into the positive (+) lead that goes
to the BMW accessory outlet. We tapped
into the accessory line as it ran forward, near
the ABS pump. We routed the small fuse on
the yellow wire to a point where we could
inspect or replace it without the need for
removing the gas tank.
(On our bike we have a second auxiliary
power outlet that runs forward to the front
fairing – if you don’t have one of these you
can tap into the power outlet under the rider’s
left leg.)
Centec Fuse Panel
Because we run auxiliary lights, electric
clothing, radar detector, GPS, and a host of
other accessories, we need a fuse panel that
can handle all the circuits and still work
independently from the BMW wiring system.
The Centec AP1 and AP2 fuse panels are
perfect for this application because they’re
capable of 8 different circuits and 5
independent fuse ratings. They’re available
from BestRest for about $55.00
Refer to our website for a schematic of these
fuse panels.
We mounted the Centec just above the
battery, on the back of the plastic air box.
We drilled 4 small holes in the air box to
mount the Centech. When we finished
drilling the holes we removed the air filter and
cleaned out any debris generated by the
drilling process. This is a very important
step, otherwise small plastic shavings can
clog your fuel injection system.
We picked up our "hot lead" for the IPF relay
by tapping into the positive (+) side of the
BMW accessory socket. This is described in
the column to the left.
If you choose not to use a Centec fuse panel,
you can connect your harness directly to the
terminals of the battery, according to the
instructions that came with your lights.
It's a relatively simple matter of routing the
power cables to each light, and routing the
on/off switch to the handlebar. Use zip-ties,
work carefully, and be neat and orderly in
your wiring. Check your work carefully before
you hook up your circuits to the battery. You
seldom get second chances when you make
a mistake in a wiring system!
Replace the body panels. Make sure all
mounting fittings are properly installed to
keep the panels from coming loose.
Following is information on
removing the gas tank from a
standard R1200GS.
These drawings differ from what
you’ll encounter on the Adventure,
but the principles remain the
same.
Refer to the official BMW service manual or
CD for complete instructions.
Drain the tank before beginning this
procedure, or at the very least ride the bike
until it’s nearly empty. A full Adventure gas
tank weighs nearly 90 pounds, so you don’t
want to be lifting it off the bike while it’s got
gasoline in it !!!
