Hey There, I have an electronic exhaust cutout I got for christmas...I stalled the switch and the led light. Grounded it and connect the postive wire into my fuse box. They said to choose a power source that is used when the key is turned to the "on" position...so...I put the postive wire into the injector fuse (1991 Z28 5.7 L98 TPI).....I've had on hooked up for 2 days...I went out to start my car...and my battery is completely dead...?? The fuse that I hooked the postive wire into should have worked...cause it only woked when the ignition was turned to the "on" position which controls the injectors. So......what other fuse could I hook this into so it won't discharge my battery??? Any help would be greatly appreciatied. Thanks

 

maybe try the a fuse thats used for interior stuff thats has 12 volts when the key is in the on position..

 

Not sure about your car but on mine there is an ACC plug on the fuse block...
