I'm looking for the KTS-Y for Kenwood KTS-MP400MR with a KTS-RC100MR remotes, I would like to add a second remote that I bought dirt cheap but I can't find the Y cable that aloud to have the 2 remotes plugged in at the same time, anyone have a clue or one for sale?? I have called Kenwood and other companies with no luck, Any help is greatly appreciate it.
