I'm in the middle of installing a monster tach, and the instructions say to connect to the positive side of the ignition switch. There is only one wire coming out, so i connected to that, and it was obviously the wrong place. (the tach didnt work, and every time i opened the door, it beeped at me to take my keys out of the ignition, and they weren't even in the ignition) So, for those of you that have installed a monster tach before, where do you connect to the ignition switch?
