I have my STI hardwired to a toggle switch that is then controlled by my ignition (when I turn the key off my sti turns off). Now when I get in my vehicle and turn the key to the run position the Sti turns on but when i start the car it turns back off for a second while the motor starts and then turns back on the the engine is running. Sometimes the startup sequence on the Sti doesn't even finish before it is turned off and then on again. Is this rapid off and on bad for my detector? Should I only turn it on after my vehicle starts and is it okay to just cut the power to the detector or should I turn it off first?
