04 MICU replacement

[kaabob]

Has anyone replaced the MICU (multiplex) before (instructions and where to buy?? I've fried mine trying to hook up LEDs to my interior lights.

EDIT: According to Vapor40,
...it's suppose to be the entire fusebox listed as illustration no. 7 (Honda Part No. 38200-SDB-A21):


Any help would be great!

EDIT 2: Alright after more researching (thanks to alldatadiy.com), I've confirmed that the mutliplex is in the drivers side cabin fuse box, and the problem is probably the multiplex... as shown below

Multiplex controls
(note input signal: door switch, output signal: door courtesy light)


Diagram of the under-dash fuse/relay box
(Note: MICU built into the under-dash fuse/relay box)



Just like to share my findings =) Now to hunt down the part, and directions for replacing the entire cabin fuse box...

Well it's been awhile, but I'm happy to say that I installed it and the door works perfectly now!

don't know if you are still around, but where did you buy the MICU? and was that the true culprit of your problems?

Ignore the pic I posted on the first post - seems like it got screwed up and I can't edit posts either

I bought the MICU off eBay, and yes it solved my door light problem.
Make sure you get the right MICU - sedan vs coupe or you will have the same problem with the rear doors on sedan with coupe MICU!
