Hey guys I installed a voltmeter in my car and I need a switched source for it to source from. Right now it's just connected to a constant battery source on the fuse box.[/b][/list]

your on the right track!

all u need to do is use a test light to find a source in the fusebox that only comes on with the ignition and your good to go

Use either a spot in the under dash fuse box that's for a accessory or the windshield fuse the radio fuse the cigarette lighter. Pretty much anything that turns on and off with the key will work.
