Our take on the XpressKit 528T Relay Module by Crutchfield's Gabrielle Thorndyke
Get more out of your Python security system with accessories from XpressKit. These handy add-ons let you incorporate luxury, security and convenience features into your vehicle.
XpressKit's 528T module is a timer-controlled relay for your Python or Viper alarm system. It temporarily connects or disconnects circuits for up to 90 seconds, so you can customize your system to allow several applications to trigger in a timed sequence or to allow features like delayed arming. It'll handle a current draw up to 15 amps or can be connected to an external relay up to 30 amps. The unit activates with either a positive or negative trigger input. Warranty: 1 year
Note: If you know how to use a multimeter and have experience working with your vehicle's electrical system, you should be able to install this car security equipment. If you're unfamiliar with installing car security equipment, please call 1-888-955-6000 to discuss your purchase with one of our Advisors.
