After much testing, we have developed a solution that uses a Porsche 997 wiper motor and a cable which connects the square plug to the correct flat plug for the new wiper. This conversion will help keep your Porsche windshield clear and clean for another forty years!
Worked well overall but not all speeds worked for my 85 944. Could be on my electrical side. Install was relatively easy and next time the motor goes out its a simple fix with an easy to find motor.
