Connecting Serial Data from ERR Cruise Commander

The easiest way to determine which wire carries serial data is to connect the tether to the engine and use an ohmmeter between pin 24 of the R2LC and the 4 wires from the tether in the tender.

Did you actually install a Cruise Commander or a Cruise M? The upgrade could have been accomplished with a Cruise M

Thanks Pete. I will get on that. I found a couple of left over" plugs that plug into the output of the Cruise Commander in my junk box so the connections with the cruise commander are taken care of. Yes, I did install a CC. I had approached my customer about using a Cruise M but he decided to spend the extra 30 bucks and go with the complete upgrade.

In that case, the full Cruise Commander has serial data on the 4-pin white connector that goes to the sound board.  It's the right hand pin looking at it from the side.

Thanks John, I was able to ascertain that from the pictures in the RS instructions. Now I THINK I have the correct wire of the tether. From a diagram you posted some time ago, I see pin 10 on the audio board receives the serial data. By using my ohm meter I found it is the red wire on the tether that goes to pin 10.
