First you have to be running 12 volts (which I am). Second you have to cut off the corner of the lower bracket of the wiper motor to clear the lip on the firewall. The 51-54 Briggs built bodies have the lip right in the way. So that is why the bracket has to trimmed. Next the round portion of the motor housing hits the lip and interferes with the mounting. So you have to (purists look away), bend a small one inch porting of the lip up about 1/4 inch. Basically the lip normally rolls down at the edge. So where the housing hits the lip, you have to straighten the rolled portion. This is only about a one inch section that is completely hidden with the motor in place. Plus it can be bend back into place easily if needed. I gently used a pair of vise-grips to do this.

Then it is simple a matter of hooking up the small wire to the mounting bolt, and the longer wire to switched 12v source. Then of course you need to hook up the metal cable from the old wiper motor to the new one. I just needed to lubricate the plastic switch slide on the motor, and adjust the cable. It works like a champ. This conversion is perfect for my driver, non-show car. I can easily convert it back if needed, and the old wiper motor covers the required bend in the lip.
