I'm not sure which part you mean; otherwise I'd be happy to, but be warned it may be a while before I get to it. I urgently need to get the front diff and cooling fixed on my JDM before I can start tearing up the USDM car's interior.
No problem its situated under the passenger side opening storage box on the JDM's you have to remove the cover completely then open up the heater/fan unit.
I'll take it apart this week-end and let you know.
