Have to remove my install of the ILP. Don't have the install instructions and couldn't find any on the net for my 2005 Z4. Had it hooked into the radio. Not sure about plugging the radio connector back into the radio; that is, do I simply remove the ILP's connector and plug the radio's connector into the back of the radio? Or, are there some other wires that I need to know about? I forgot whether or not I had any wires into the fuse box and was there a ground wire?
