Installation:
Caution: Mounting will require drilling. It is absolutely necessary to
make sure that no other vehicle components could be damaged in
the process. Check both sides of the mounting surface before
starting. If damage is likely, select a different mounting location.
295SDA1 Module:
1. Locate a suitable mounting location. A dry, cool compartment is a
good choice.
2. Position the unit on the proposed mounting
location. Using an awl or similar
tool, scribe the mounting surface
where the mounting holes are to be
drilled. Make sure that this
mounting area allows sufficient
ventilation for the unit.
3. Remove the unit and using a drill
bit sized for a #10 sheet metal
screw, drill a hole in each of the
areas scribed in step 2.
4. Return the unit to its mounting location and
using #10 x 3/4” sheet metal screws (provided), secure the unit onto
its mounting surface. Be sure to install a #10 internal tooth lock
washer (included) onto each mounting screw before mounting the
unit. IMPORTANT: The 295SDA1 case must be either mounted on,
or grounded to the vehicle chassis.
Control Head:
There are two basic mounting brackets for the 295SDA1 control head.
One allows the control head to be mounted into your vehicle’s console (if
so equipped). The other allows the control head to be mounted directly
onto the dash or other surface through the use of a bail strap mounting
bracket. Regardless of the style selected, be sure to observe the air
bag warning on the cover of this manual.
Bail Strap Mount:
1. Position the bail strap in
the selected mounting
location. Using an awl
or other suitable tool,
scribe the surface
where the mounting
holes are to be drilled.
2. Drill the mounting holes
in the areas scribed in step 1.
The size of the drill bit should be
determined by the size of the
mounting hardware (#10 sheet
metal screw) and thickness of
the mounting surface.
3. Using hardware provided (#10 x 3/4” sheet
metal screw & #10 internal tooth lock washer)
secure the bail strap to the mounting location.
NOTE: There are 3 sets of holes on the bail strap for positioning the
control head at 3 different heights.
4. With the bail strap in place, insert the #10 x 3/8” hex head bolt into
the assembly hole from the inner side of the bail strap as shown.
5. Place the #10 internal-tooth lock washer and the acorn nut on the
protruding bolt on the outer side of the bail strap. Loosely secure the
acorn nut to the hex head bolt.
Slide the control head onto the bolt heads. Once it is in the position that
the customer has chosen and the control head has fully engaged the bolt
heads, tighten the acorn nuts until the unit is firmly secured.
A third pair of mounting holes are provided that will enable the control
head to be located much closer to the bail strap than the other pairs allow.
If this closer location is used, the tips of the bail bracket may be broken off
at the notches.
Control Head Cable:
Route the control head cable (provided) from
the amp/relay module to the designated
mounting location. Plug this cable securely
into the rear of the control head. Be sure to
route the cable through either of the two
recessed pathways (shown here). This will
prevent the cable from being accidentally disconnected
or pinched by the control head.
Havis Console Mount:
The Havis Console mounting kit includes all the necessary hardware
needed to secure the control head to the mounting bracket for installation
on a Havis Console. The control head mounts onto the console mount
bracket the same way the control head mounts onto the bail bracket as
outlined previously except for the addition of a flat washer that must be
inserted between the control head and the bracket. Please refer to the
manual included with your console for specific information on securing the
control head/mounting bracket assembly onto the console.
