Hi, I purchased a 3 wire accessory cable for my control box, planning to hook up a tach. Wondering if I can power anything else other than the tach with the cable? I'm also installing a voltmeter, 12v outlet, fish finder and stereo. Can these be powered with the same cable? I don't want to mess up the tach reading and I don't want to overload it, just thought it would be ideal to have them all hooked to the ignition source. Thanks for any input!
