pressure transducer swapping step-by-step?

[auditude at cox.net]

Hi,

Is there anything online as far as instructions for swapping the pressure transducer in the 
(Motronic) ECU?  It doesn't seem the actual procedure would be too difficult, but then again 
it's not something I want to take lightly.  I was thinking maybe there would be an online 
resource from someone who's BTDT?  Of course, if I'm not confident and comfortable about 
doing it I'll have a pro do it.

Thanks,

Ken
