OK, so I screwed up. Bought a newer Bobcat snowblower with the 7-pin connector to run on a 12 year old skid-steer without any electronic controls. I knew I'd have to add controls but was thinking more along the lines of 12v switches, not computerized controls. Also, the blower has 3 hydraulic lines. My skid steer has a pair of high flow and pair of low flow connections but don't know what the 3rd line is for. I think I've searched this forum well but maybe not. Any help anybody can give me on getting this thing to run would be greatly appreciated.
