Boxster Wiper Motor Options

[McMark]

Just bought a wiper motor off a 2003 Boxster to see how interchangeable they are with ours. Modern speed wipers is on my list of things to make the 914 wife-worthy.

Pictures and thoughts once the part arrives later this week.

*Looked a Boxster seat belts as well. (IMG:style_emoticons/default/idea.gif)

Differences:

- The wiper linkage arm on the Boxster is longer (the gold piece below, pic from boxster). This means the 914 pieces may move faster then the Boxster. But that's a good thing. I can slow down a motor, but I can't speed it up.

- The bolts and drive shaft on the 914 motor are longer to allow the motor to clear the bracket in two place.


First the 914 bracket will bump into the Boxster motor. This can be clearanced easily with a grinder.


The second is the linkage drive arm will bump into the rubber mount. There is a little bit the can be removed from the arm and a little bit that can be removed from the rubber mount. This should clear. Worse case scenario, I can cut and weld the drive arm to have it run higher up. I don't want to do this because that will also make some undesirable forces that could lead to unexpected failure later on in life.


- Wiring
The red wire is the fast speed and the green wire is the slow speed (motor body is ground). The three unwired connections are the motor park connections. They look like simple pass through connections (which is what I thought they were), but I took off the cover and discovered connections inside that correspond with the connections outside. The center pin (#2) is the common rail. The inside pin (#3) is disconnected at the park location, but connected the rest of the rotation. The outside pin (#1) is connected at park and disconnected the rest of the rotation.
