Okay after looking at the diagram, it looks like the part is accessible from the trunk. If that is the case I should be able to install it (unless it needs to be realigned after installation) as 'markwb' mentioned in an earlier post.
That would save me a chunk of CDN $$$$
Do you guys know if it needs to be set up or is it just plug and play?
Just install the new one the same way the old one came out. Electrical connector orientation would be a clue etc. You may be able to get at it from inside the trunk, maybe not. There'* not really any alignment procedure after replacement of the yaw rate sensor, however, the FSM directs you to conduct an ABS diagnostic system check.
Basically, if the DTC'* can be cleared after sensor replacement and stay clear, you're okay.
