This part is off the wiring in my boat. I was told it works as an amplifier to increase the voltage going to solenoids in the exhaust to change from quiet to loud exhaust. The 12 volts from the battery has to be increased to roughly 40 volts to activate the solenoids. First, does anybody know the name of this part? And second, any ideas where I could buy a replacement? The manufacturer of the exhaust system is Corsa but they do not sell just this part...only a replacement wiring harness for around $500! Thanks.
