How do I get the coil pack off?

I don't see how it's possible to remove the nuts on the back of the plate. It seems difficult, but possible to get the one on the alternator side using a 13mm wrench, but the one on the master cylinder side I have no idea. The cabling seems to be in the way. It does not seem to budge, if it was movable, I could probably use a ratchet.

I reached down behind the coils, and put a deep well socket on, with my hand in the open space behind/under the coils.

Also look for any little plastic clips that might be holding those wire packs in place.

OK, I got it off. sems to me the trick is to undo those wiring clips, then manhandle the wiring harness pieces until you can get a deep welled socket in there.

I had no problems with this:

1/4 drive rachet, small extenion bar, 5.5mm socket (not a deep)

Did all 3 in work's parking lot in 25 minutes
