CONSTANT POWER (+12V, key in any position including off)
This system operates on constant 12 volts, the system also needs a source of power that is only on
when the ignition is turned on (usually referred to as “Ignition Power”.
1. Locate the wires going to your vehicle’s ignition switch (usually located coming down the steering
column). When looking for constant 12 volts: Usually a large gauge wire located at the ignition
switch harness. Probe these wires until you find one that turns a “computer-friendly” test light
, or shows 12 volts when the ignition switch is turned to the ON, OFF, START and ACCESSORY
positions. If this wire cannot be located at the ignition switch harness, run at least a 16 gauge
wire from the positive battery terminal fused at 6 inches from the positive battery post to the
inside of the vehicle through the firewall. (additional hardware is needed.)
2. Mark this with its function “Constant Power”.
3. Turn the ignition ON. Probe for a wire that shows 12 volts only when the ignition is on. Confirm
this by turning the ignition on and off while probing each wire.
4. Mark this wire with its function “Ignition Power”.
5. If these wire cannot be located, please call our technical support staff at 800-878-8007.
