Matt, don't want to hijack the thread. See my last reply above.

Yes, the plastic bracket and auxiliary fuse panel does not have to removed to R/I the CDM. I posted instruction as far as the aux fuse panel and bracket went in case the OP was trying to do something other than just R/I the CDM. I "borrowed" this image of the bracket from Ebay.

Sorry if my first reply wasn't as helpful as it should as I forgot to mention the retainer clips. However what I wrote is what you may want to try - considering the clips need to be unlocked.

If removing the fuse holder is your goal you will - according to my own experience - first have to clear grounds around it get clearance to the CDM holder.

Matt,

Goal is to remove CDM.

Problem is the 4x2 fuse panel is prohibiting me from moving the plastic bracket that's underneath the CDM, so I can see to finish removing the CDM.

That's why I was asking about removing the fuse panel from the plastic bracket.

Any suggestions/tips on how to move the plastic bracket out of the way is greatly appreciated.

Thanks,

Gary

I don't understand how it's possible to pull the CDM NIGHTMARE out of the car from the side. And it's been so long since I've done this I don't recall any fuses in that location.

Jeff, I am referring to the fuse panel on the passenger side of the dash in my posts. To make it clearer, it is the fuse panel that the passenger door closes up against.
There is also a smaller fuse panel under the passenger side dash, but I did not disturb it or any of the connections in that area.
If you remove the cover and trim panel from around the fuse cover the passenger side of the CDM is visible. No trick at all to remove the nut and connectors by working from the side of the dash. The drivers side of the CDM is attached the same way. Not easy, but can be released by reaching up from underneath. Remove the nut and the 2 connectors. The connectors must be removed before trying to move the CDM.
With everything loose, push the CDM towards rear of car, lift front of CDM and work towards front of car. When it is clear of the attachment clips it can be worked down and out the side of the dash around the fuse panel.
I am not saying it is easy, but can be done. Dr. Don talked me through the procedure. I went with his advise as I figured he had done it probably more than anyone else.

This isn't the CDM bracket, that bracket holds the computer under the hood.

I wish I had known I could be removed this way,I did it by pulling it out from the footwell,never again,it goes out I'll out a nice system in the car.

This is the release tab, at the tip of my screwdriver. Push it in with a small screwdriver and slide the holder upwards against the CDM tray.

I just had to pull my CDM again for another overhaul.
Took me about 10(!!) minutes to do the job. Unlike during the first attempt I didn't unplug the harnesses under the CDM. Just removed them from the plastic clips that attach them to the CDM tray.
Auxiliary fuse holder easily slides out upwards once unlocked.
Then I pushed the CDM forward, removed the 2 locking Nuts and all attached wires, pulled it into the footwell and ... job done.
Terribly easy considering my painful first attempt.
Anyway, getting it back into place should become way harder. 20210716_212932.jpg
