Hi there. I battled for a while trying to figure this one out. I don't know anything about Skip's SES2. what I wound up using is a Robbe Duo-Switch, and a Duo-Switch Memory, so two relay units total. I also made my own daughtercard that I mounted the lil sucker to. Those tiny wires were just too small to be trying to solder or desolder to during the figuring out stage. I used some small Dean's connectors on the daughtercard so I can unplug the wiring anytime without affecting the actual sound module.Finally got the whole thing to work properly!
I have some photos of what I did as well. If you're interested, contact me.
