I have it hooked to the radio fuse should it be hooked there or the ignition fuse I do know it says to wire to either fuse box or brown ignition wire
I do not remember the connector I am using got it from walmart but it does say to hook to a fuse being the 2005 g6 uses a data wire to turn off and on the radioAre u using the pac gm11b, it would hook up directly into ur harness plug and play
