INSTALLATION PROCEDURE
It is virtually impossible to predict the exact installation proce-
dure for every different type of vehicle on the market. There
are some details that will have to be worked out on the spot
with your particular vehicle and here are a few ideas to con-
sider.
There are five parts to consider when installing the OMD: 1)
The crossbar assembly, 2) The power box, 3) The cable assem-
blies, 4) The display unit, and 5) Vehicle Grounding Strap.
Crossbar installation:
The OMD components are pre-aligned at the factory and
should not require re-alignment when the system is installed on
the vehicle. It is, however, important that the u-bolts be at-
tached in such a way that they do not bend the support rod.
The u-bolts should be tight enough to hold the OMD crossbar
securely in place, but not so tight as to distort the crossbar. If
that happens, re-alignment may be required. We recommend
using only two insulated u-bolts to mount the OMD crossbar to
minimize the possibility of distorting the crossbar. The follow-
ing procedure will generally work best.
For your convenience, we have put together an OMD mounting
kit, which includes strut channels, shelf brackets, u-bolts and
mounting hardware (Heath P/N 2510651).
Use two strut channels that are approx. 24” long each (Heath P/
N 2510652). These strut channels are mounted vertically to
the front bumper of your vehicle, parallel to each other and
approx. three feet apart. It is most fortunate if you have a front
bumper that is relatively flat vertically, in which case the strut
channels can be mounted directly to the bumper. If the bumper
