Installing new radio - need to connect to parking brake wire?!

Did anyone ever figure out where the parking break wire is? I have a JVC KW-Z1000W and I've tried everything except connecting it directly to the parking break wire. Tried a ground, toggle switch, parking break bypass, etc. None work for me. Bought this unit from Crutchfield who won't assist me or return the unit until I've tried the actual parking break wire connection as it's supposed to be done. I just can't seem to find this wire to connect the wire from the headunit to.
