I have the instructions for a 2007 model. Pretty straightforward, if longish. It involves removing the sliding door, trim panel, HVAC unit if on the right side, some other stuff...
Let me know your email in PM if you want to try your luck with the 07 instructions. Otherwise, you can get the 05 instructions at techinfo.honda.com for the 3 days @ 10$ subscription.
That being said, what is the problem?
Edit: Just saw your other post. There is a TSB titled "Power Sliding Door Stops at Half-Latch Position, Won’t Close". Sounds like what you desribed... If the door closes partly then reopens, I would think it is not a motor problem.
Mine actually almost closes all the way but starts to "shutter" a bit towards the end of the close cycle and just before it closes, it reopens. I read the TSB and it is not written in layman's terms. I am going to pm you.....thanks .
