INSTALLATION INSTRUCTIONS
Radio Power-Off Delay – Part Number 12007
Congratulations on your purchase of this Radio Power-Off Delay. Adding this controller to your
radio power supply line will enhance your vehicle experience. Whenever the switched power line
is on, the radio power will be on, but once the switched power is turned off, the radio power
remains active until a door is opened or 15 minutes passes. Installation of this unit will require
you to know how your radio is wired into your vehicle harness or the patience to figure it out.
Installation may be easier if you have access to a digital voltmeter.

Mounting the Unit
The Radio Power-Off Delay may be mounted in any location where the electrical connections are
easily accessible. Mounting in a weatherproof location is recommended. Use two self-tapping
screws, rivets, or zip-ties through the mounting tabs to securely mount the unit.

Electrical Connections
The Radio Power-Off Delay needs connections to constant power, switched power, the radio
power lead, the dome light ground wire (to sense when a door is opened), and a main ground
lead. Figure 1 shows a basic schematic of how the unit should be wired.
Red Wire
Connect this wire to a CONSTANT power source. This wire must have battery
voltage at all times (even when the key is off). The supplied female connector
can be used to attach this wire to a switched 12v source on the fuse box. This is
where the radio will now be getting power.
Black Wire
Connect this wire to a good vehicle ground. The small ring terminal can be used
to attach this wire to a mounting bolt or another source of vehicle ground.
