Sorry for the breif reply. I wanted to check it out last night, but after I grabbed a mirror and a flashlight and started to head out, a huge thunderstorm thwarted my efforts. It cleared up sort-of. I'm going to check it out today and know for sure. I'm hoping to just see a socket for a relay. That would be sweet. I brought the flash light and mirror with me, so I'll see at lunch what the deal is with it.
