I'm going to be installing Z2 in the next week or two weeks. I've done headunit installs before, just none with navigation. I've researched and come up with that I'm going to have to do the 2 wire mod, as well as put a resistor in there to eliminate any popping upon shutting the vehicle down since I've got the "Shaker 500" system. The only thing I'm un-sure about is the VSS. The VSS in these cars isn't behind the dash, it's at the PCM. It's PIN3 on the top plug, it's a blue/yellow wire, if anyone else needs to know. However, how am I supposed to tap into it? Just use one of these?

Thanks in advanced guys.
