I was finally able to install command control in my Williams FM, and I have the ERR Railsounds commander as well.
Problem is, I acquired the Railsounds commander when I was using conventional only, and had to cut the power and data cable to modify it (I also discarded the then-unneeded portion). ERR doesn't show it on their web site, only the older style cables. I need the one that has 3 plugs, two black wires, a red wire, and a purple wire.
Any ideas where I can get one?
Thanks.
