I hooked up my HS E revolution sound controller yesterday and wow is it awesome. Since I have an 09 there is no analog tach wire at the helm so I had to run a wire from my motor up to the helm and h s e. There is the 16 wire engine harness that hooks into the boat harness which goes to the helm. In the engine harness there is a grey wire that is the indmar analog tach wire. On my 09 this wire does not go up to the helm so it is empty on the boat side of the harness connection. For now I just inserted my wire into the empty boat connector with some electrical tape until I get the proper pin to use. Running the wire up only took about 5 mins. I'll post some pics and and a short video when I get home.
