I recently had a Kenwood KDC-X696 installed in my 1984 Mustang GT and since then my electric windows, wipers, and dash clock all stay on and drain my battery. Cartoys, who did the installation, said it had to be the new igntion cylinder I had just installed two weeks earlier. I replaced that, again, and I'm still having the issues. They took it apart and looked at it and couldn't figure it out. Any ideas?
