Mounting Holes

Mounting Under Instrument Panel

1. Position the controller under the instrument
panel to the left or right of the steering
column, based on available space and
driver preference.

Mount on Either Side

Figure 1

2. While sitting in a normal driving position,
place the controller so its handle is within
easy reach.

3. Remove the controller cover and, while
holding the controller in place, select at least
two holes through the case which best mount
the controller. Mark the underside of the
instrument panel through these holes.

Hydraulic Connection

1. To provide for automatic actuation of the
controller, a branch tee must be installed in
the hydraulic brake system. Tees are not
furnished with the controller kit because
requirements vary with different makes and
models of towing vehicles. To determine tee
size, measure A and B dimensions from the
towing vehicle’s master cylinder as illustrated
in Figure 3.

4. Drill 3/16" diameter holes where marked,
being careful not to damage anything under
the instrument panel.

5. Attach the controller with 3/16" bolts, nuts
and lock washers, and tighten securely. Bolt
heads are to be inside the controller.
