Revolution Electronics Radio Power Controller for Classic GM and Chrysler vehicles

New luxury vehicles often include a feature to keep the radio power active after the key is turned off; the radio doesn't shut off until you open a door. Now you can add this effect to your classic car or truck. By adding an external relay, you can wire it to control all accessory power, not just the radio, so you can stil operate the power windows or other accessories. This model designed for vehicles which control the dome light by switching the negative side of the dome light circuit (classic GM and Chrysler vehicles).

• Controls a vehicle's radio power line to keep the radio active after the key is turned off. Could be wired to control all accessory power.
• Monitors the dome light circuit and shuts the radio off when a door is opened. If a door is not opened within 15 minutes, the radio is shut off to preserve battery power.
• Designed to work with vehicles that switch the dome light on and off by switching the ground side of the circuit (such as classic GM and Chrysler vehicles from the 60's and 70's).
• Includes an internal self-resetting 7 amp fuse. By using an external, high amperage relay, this module can be wired to control all accessory power, not just the radio.
• For 12V vehicles which control the dome light by switching the ground side of the dome light circuit (classic GM and Chrysler vehicles from the 60's and 70's). 2 by 1.5 by 1 inches. Fully potted. Made in USA.
