A wire was run from pin #1 at the radio to pin #18 of the dual relay for the cabriolet top. The mod has been well documented and I now have automatic increases in volume as the car goes faster. My question is kinda techical: What is the signal pin #18 emits ? I want to install a CDR in my 914 and would like to figure a way to duplicate the signal. The first thought was to consider the Tach signal. Any eletrical geru's out there ? Thanks, Jim
