B&M 46076 LAUNCH CONTROL KIT - Manual (Page 3)

drawing that matches your brake
system. The size of the tube nut
measured across the flats with the
gauge indicates the size of the female
threads in the distribution block or the
differential pressure switch block. You
must use two female fittings for the
launch control solenoid valve, one for
the inlet and one for the outlet. These
fittings will have a male 1/8" NPT
tapered pipe thread on one side. If a
male connector is called for on the
diagram of your sys-tem, you want a
male connector with the 1/8" NPT pipe
thread on one end and a flare fitting with female threads the same size as
the threads that was measured with
the gauge. Where a male branch tee
is called for on the diagram, you want
a tee fitting with a 1/8" NPT male pipe
thread on one end and flare fittings
on the other two sides of the tee.
Step 2. Install the male connectors
and/or male branch tees in the correct
ports of the solenoid valve. In all cases
the Master Cylinder connects to port
labeled “IN” and the line to the brakes
connects to the port marked “OUT”.
Mount the valve in a position that
locates the connectors close to the
line to which they will be connected.
The mounting position of the valve is
not important. Using the holes in the
bracket of the valve as a guide, drill
two .185" (No. 13 drill) holes for
mounting.
Step 3. Install a new length of steel
brake line tubing in the specified
location and reroute the existing brake
lines. When bending brake line use a
tube bender to avoid crushing the
tubing. If an existing brake line must
be lengthened, a flare union must be
used. Where there is an unused port
in the distribution block or pressure
differential switch block use a steel
plug designed for flare fittings. These
plugs, like all of the tube nuts used in
the system, have straight machine
threads, not tapered pipe threads. Do
not attempt to force a tapered pipe
plug or fitting into a port with straight
threads.
ELECTRICAL INSTALLATION
Make sure that all electrical
connections are properly joined
together by either soldering the
con-nection or by using a crimp-on
