Look at it, the motor will either have a wire or vacuum line to it. But I think the linkage configuration described above is the same. Wiper arm comes off by releasing a clip under the "cup" and pulling it off. If it has been on a long time can be a challenge. Take is slow and do NOT bend or twist the arm or "cup", they are pot metal and can crack pretty easily or you can loosen the splined part from the shaft. They make tools to take them off, but careful use of a small flat screw driver works, I alway tape the paint around the are in case something slips.
