12.5 TRUCK CAB CABLE ROUTING
The RSCB is supplied with a cable assembly, consisting of two cables, which connect it
to the truck computer.
The two cables are terminated on the RSCB end with connectors that have been routed
through RSCB hubs and connected to the RSCB circuit board at locations J1 and J6.
On the cab side of the cable assembly, the two cables join in a black 16 pin circular
connector. This connector is supplied with a red plastic cover, which should be kept in
place during the installation. The cable is available in a variety of lengths, ranging from
25 to 500 feet. In most cases, the RSCB is shipped with these two cables attached. If
the cable has not been terminated and connected on the RSCB end, you should connect
the wires to terminal blocks J1 and J6 per the wiring diagram in the back of this manual.
The black cable has a drain wire and a foil shield that must be cut off even with the outer
cable insulation. The edge of the foil must be taped with electrical tape to ensure a
proper floating shield. (The drain wire is connected to pin 16 on the truck computer end,
which in turn is connected to chassis ground.)
q
Install all exposed cable in ¾”
automotive plastic corrugated loom
(wire tubing).
q
Run the cable down the inside edge
of the truck’s frame rail.
q
Secure the cable to the frame rail
every 18 to 24 inches with wire ties.
q
Install rubber grommets to protect
the cable where it passes through
the cab wall, meter box, etc.
q
Keep the cable away from heat
sources such as the engine exhaust
manifold, exhaust pipe, mufflers, etc.
q
When routing the cable, avoid
suspension parts, springs, shocks,
rotating shafts, linkages, etc., which
could crush, pinch, or rub the cable.
q
Avoid installing the cable where it
will be exposed to excessive flexing.
q
Do not pull the cable too tight in
areas where it will be moved. For
example: in cab-over trucks, leave
enough slack in the cable so that the
cab can be tilted forward without
damaging the cable.
q
Leave enough slack in the cable to
allow for easy removal and
installation of the Supervisory
Console and RSBC should they
require servicing.
q
In the meter box, avoid leaving the
cable unsecured. Be sure that it
won’t be snagged when tools or
other items are moved. Keep loose
cable from lying on the meter box
floor.
q
On some trucks, extra harness cable
can be secured in the frame rail.
Otherwise, coil up extra cable and
securely fasten it to the back wall of
the cab.
DO NOT place cable on
the floor of the cab or where it may
be damaged. Also,
DO NOT attach
to cable seats that can be moved.
We recommend that the following installation practices be followed when
routing the cables to the cab:
