For the Sears openers you will have to use the "mini" remote as there isn't much room under that cover. I bought one from E-bay for $17 including shipping and about another $5 for the switch.
Works like a charm. Now I don't have to spend all that energy putting down the kickstand and walking 12 paces to the inside door switch. Whew!! The first day home after install it was sprinkling as I came up the drive, it was all smiles.
