Hello all. Something interesting that I discovered while trying to find a replacement headlight control unit for my 997 headlight. You can use a Toyota part # 85967-08010 or 85967-50020. This should be direct replacement for 997.631.283.01 and 997.631.183.00. You can find these new for around $125 vs. $500 from Porsche. I bought a used one for $50 just to make sure it worked. I did a search here to see if anyone else had discovered this, but found nothing, so...here you go.

Here's the original Porsche part in the right headlight:


And here's the Toyota part mounted in the left unit:

 

Good find!!! Since the 997.1 headlights are made in Japan, it makes sense that they would use commonly available parts also used by other Japanese manufacturers.

Now, the difference in price is just the Porsche mark-up. Nothing to worry about....

Nice find! I hear that the transmissions are also made in Japan.. :P

 

That is true. It is an improved Camry gearbox.....
