To connect filter assembly to power
source of other affected electrical/
electronic components:
1. Disconnect vehicle battery master switch or
vehicle battery cables.
2. To install unit:
a. Select location to mount filter within 12 inches
of power source on the affected component.
If location within 12 inches is not practical,
B+ connecting wire can be spliced to increase
distance up to 2 feet from power source on
component. Increased wire length reduces filter
effectiveness.
b. Secure green ground wire (see Figure 1, page 1)
from unit to grounded surface, using one
mounting hole in unit. Use second mounting hole
to finish securing unit to mounting location.
Unit MUST be connected
properly to grounded
surface directly back to
battery negative terminal.
3. Connect “B+” connecting wire from unit to compo-
nent power supply, splicing B+ wire length if
required from step 2a. See Figure 2 on page 1 for
stacking order.
4. Reconnect vehicle battery master switch or vehicle
battery cables.
5. Operate engine and check component operation.
