- About This Product
DescriptionBefore the days of your truck having a module-for-this and a module-for-that, an owner would simply tie into an ignition "On" power source and power a relay to add additional circuits.
With the Rostra SourcePWR you no longer have to poke and prod for the ignition on signal. The SourcePWR goes directly to the battery and it is triggered on and off (a smart logic circuit) by the voltage drop when you engage the starter. The SourcePWR can then be used to add a 7.5amp circuit to your truck.
