its the batt wire. its wired into the ignition wrong is all. personally id run it straight to the battery on a sepearte circuit and have an inline relay. that way you can make it turn off or on when ever you want.

[sweetshee4312]

if i ran the battery wire right to the battery where would i run the acc wire too?

[racer]

depends on what you are calling the acc wire? is it blue? if it is its the wire you use to fire up your amps.

[banshee x]

no the acc wire would be the red one,also like a ign wire(switched power) when the key is on current passes to this wire thus giving your head unit power when installed correctly.if you want to hook straight to the batt. you just hook both wires to the batt or the starter relay(big-2-4 gauge wire coming from battery to relay),and make sure you put an inline fuse on the yellow wire should be labeled batt in the harness coming from the head unit.Dont hook up the illumination wire that might be a problem on that old of a vehicle(orange/yellow wire)......I would suggest hooking the batt/yellow wire directly to the battery w/in line fuse(30 amp green),and go to your local auto parts store/stereo shop and buy a connector that goes directly behind one of your fuses (from the fuse box to something like your a/c,heater fuse for your switched power) this connector will have a male spade to plug a wire into.put the red wire to this and your stereo should work fine.check your ground location(s),you could have a bad ground on your lights /stereo causing a problem with the two circuts.Good luck pm me if you need any more help-I was a certified installer for Clarion for about 3 years!!!

^^^^^^exactly. i was tryin to figure out which wire he means.

[bigboybanshee]

What I use to do was run the yellow wire (constant) to the battery and fuse it like suggested above, and then run a hot lead from the battery to a toggle switch and run the ACC (red) from the radio to the switch. That way I could have a switch (like the ignition) to control when my radio was on without having the key. I would hook my amps up the same way; mainly my sub amp so I could cut it off when rolling through the hood
