An addition to ptatohed's guide: on a Canadian Max there is a daytime running light relay, shown. It is possible to just bend its bracket to make room for the supercharger head unit.
The fusebox (relay holder, actually) is more of a problem. There is about a 3/4" plastic support coming out of the fusebox and into the wire loom for daytime running light relay. It is impossible to properly relocate fusebox with this in place. You need to peel back wire loom and cut off this bit of plastic. Then you can squish wire against fenderwell to make it fit.

Once the battery, airbox, MAF and everything are out, there sure is room to work! Hey, I can see my transmission: Maybe I should check on it!
My tranny had to come out due to bad diff bearings. My easy tranny sling is shown. Put a towel on each fender then a 2x4 across. A nylon cargo strap goes over 2x4, around transmission, and back. By having your helper give slack when removing tranny or taking up slack when replacing, you have good tranny support and freedom to steer it in and out of position. I like this better than a tranny jack. This work requires a lot of beer!

Kooky Amateur Mechanics!
Project rapidly increased in scope. When under the car, I found that the axle seals were leaking. I referred to mortorvate.ca to learn that it was due to worn differential bearings and would only get worse. Can't just replace seals. Here's my bad bearing. I bought new seals and bearings from dealer for big $$ and had a moonlighting transmission mechanic crack it open and install parts for only $150 labour.
perspective is a bit weird, but this is me lying on the floor steering fixed tranny into place.
