First off, REMOVE THE BLACK WIRE ON PIN-10! You do NOT want that ground going to the CC-M, it's very bad for it's health!
Next, you need the serial data going to pin-1 now.
You can use the marker outputs of the CC-M for your current marker lights. I'd pull the black loop out of the existing connector that connects pin-1 and pin-10 first! Then just pull the wire from pin-1 of the CC-M supplied connector and put it into the existing connector. That wire goes to pin 24 of the R2LC socket to supply serial data to the CC-M.
