I connected the "trigger wire" to the "key in lock" connection on the
ignition switch (the one that sets off the beeper). Now the cd/radio
comes on with the key in the ingition switch, without turning it(or you
can turn off the ignition when parked and not turn off the radio).
I forget the color of the wire, I don't have the post that I got the
info from with me. If interested, ping me back and I'll try to find it.
Or just trace the wire that inserting the key energizes.
