Electrical Connections
Make sure you have properly mounted the switch with the included
attachment hardware before installing cables, wiring, or making
electrical connections. Remove the positive and negative cables
connected to the battery before proceeding. This is for the installer’s
safety. No part of the vehicle should be energized while installing the
switch. The Big Switch 500 Series battery disconnect switches can
be used to disconnect either the positive or negative terminals of the
battery. Verify installation and wiring with the vehicle’s manual
and follow all vehicle manufacturer instructions.
1. Select two battery cables of required length for the installation.
Cable gauge size will be at the installer’s discretion depending
on vehicle requirements and specications. If the installer
wishes to cut and reuse the original battery cable, make sure
that there is enough cable to reach the switch without stressing
the cable or the battery disconnect switch.
2. Attach the two cable ends to the switch terminals as shown in
below. Tighten the M10 nuts until the lock washers atten, but
no tighter than 11-13 ft.·lbs.
3. Once the cables are installed and tightened, terminals covers
(recommended, but not included) should be applied to the
switch terminals.
4. Make sure the The Big Switch 500 is turned to the OFF position.
Connect the load-side cable to the required point on your
vehicle FIRST. Hook up the cable that connects directly to the
battery terminals SECOND. See below for clarication.
5. Turn ON The Big Switch 500 and make sure your vehicle is
powered.
FR1003TM Terminal Covers
Sold in sets of two. Can be used to
cover cables on all Battery Disconnect
Switches. Sold separately from switch.

Connection of the LED indicator should be completed at the time
the switch is mounted but before battery cables are connected
to the switch. Do not install the switch or LED indicator while the
vehicle battery is connected to the vehicle. Make sure that the area
of the chassis where the bracket is mounted has a good connection
to ground and is not insulated by plastic or paint. If this is not
possible, an additional wire should be run directly to the WHITE
ground wire to complete the circuit.
1. Make sure that the switch is installed in the bracket and mount
the switch in the desired location. Only screw on ONE of the
lock nuts.
2. Take the WHITE wire with the smaller eyelet and slide it over
the right screw. Tighten down the right lock nut so that the eyelet
is pressed rmly against the vehicle chassis for a proper ground
connection.
3. Take the BLACK wire with the large eyelet and slide it over the
screw terminal that is connected to the VEHICLE LOAD.
4. Before proceeding, make sure the battery disconnect switch is
in the OFF position.
5. Connect the vehicle load side battery cable, followed by the
battery side battery cable, and secure these connections with
the provided M10 washers, lock washers, and nuts.
6. Connect your battery cables to the positive and negative battery
terminals and test your newly installed switch.
