PCM question
Hello team, does a pcm unit from a 2002 boxster work with the factory harness in a 2000 boxster?

Yes, once the DME is programmed to the car. You can't just pop it in and expect it to work if that's what you're asking?

I would also be concerned about the 2002 use of CAN Bus, which the 2000 did not have.

Man, I wish I had known that. I had bought a unit awhile back and could not get it to work in my Boxster. I just wanted to use the head unit, not the navigation driver. My bad for not asking an expert!

I am guessing this is something the dealer needs to do/charge for?

You need someone with either a PST II or a PIWIS system to code the car for the PCM to work.

And you will need to ask your dealer to provide the learning codes (passwords).
