I have 1997 TJ and I'm trying to hook up a dummy flashing light in the dash. I need to know what wire to tap into for an ignition switched hot, so the light comes on when the ignition is off.

Are you saying you want a wire that doesn't have power when ignition is on, but has power when the ignition is off?

I don't think that exists. What you can do is get a constant hot wire and then just put a toggle switch on it

Not unless you tap into the 87a terminal on a relay that closes when the key is on like the accessory relay under the dash near the steering column. There is probably no terminal in the socket for the 87a tab so you would have to add it in.
