Re: need help installing a sub in \'93 S-15 Jimmy
What they mean by auxiliary power is power controlled by the ignition switch. that way when you shut the jimmy off, the amp shuts off as well. I can't tell ou specifically which wire you can use, but with a voltmeter, you should be able to find one by measuring voltages on each power wire with the key off and on.
