Well a small milestone today... I pulled out most of the automatic transmission wiring and the gear selector. I was looking at doing it earlier, but always seem to find another thing that was bit more important at the moment. Funny how something as simple as a hole in the floor can feel like progress. 
01P Wiring Harness and TCU
After struggling with it for a while -- I pulled the transmission computer module first, which left lots of room to feed the harness through. It also helps to bend the wiring panel holder out of the way too.

Then everything can simply be disconnected - no need yet to rip anything out from the back of the wiring panel.
What I haven't removed -- is this little bit of wiring from the automatic selector - it routes back the wiring panel under the carpet. The open connector is probably for for the shift lock solenoid -- but there is also a little "limit" switch here as well -- not sure what this is. Any ideas?
Transmission selector wiring
Itsamoto, since you went thru the process of removing A/T on your EV, I want to check with you on A/T wiring... I'm thinking on modding my 2001 EVC to do automatic door locking/unlocking as a winter weekend project. I'm planning to use some programmable micro-controller to supply +12DVC via relays to actuators ( good write-up on how actuators work is available here:
http://www.gowesty.com/tech-article-details.php?id=46 ). Just need to figure out the logic when to engage locking-unlocking.
I think either of the following would work for this purpose:
- read whether transmission in the park mode
- read whether transmission in the reverse gear
- receive notification when A/T transmission switches gears
- read the current vehicle speed from the ECU (if it's ether possible).
- read the current gear selection from ECU or TCM
I think the first two options might be easiest, just need to figure out its schematics. Any thoughts?
