This was by far the most challenging part to figure out and I looked at many different options. When you remove the backer board in the basement to access the vent pipe you will notice two vent pipes going to the roof and then connecting to one in picture shown above. There is a small gap on both sides allowing access with the entry door side having a much larger access. If I ran it behind the mirror there would be no way to access the wiring from the basement that I know of. I knew the vent pipe was behind the cabinet where I cut the access and that I could easily cut a black panel to cover it up when done. One other important point is that I spoke with GD and to the right of the vent pipe in the above picture (entry door side) is the AC ducting so I knew drilling up to the right was not a good idea. I also tried to run fish wire down the left side of the vent pipe but there is very little access on that side in basement....hence you see me wrapping the wire around the vent pipe. The other good point about this option is I can now run the wiring for the Battery Monitor and Control GX easily and mount it just above the control center.
Edit: One other point that was really helpful is to use an Endoscope to look in these tiny places. I bought one on Amazon for cheap and will show on your phone what is behind these tight spots you cannot access easily.

I thought I would make a couple comments on tools. Anyone taking on this project will need to invest in a good pair of wire cutters, lug crimper, multimeter, etc.
I had purchased the 16ton hydraulic crimper with the various dies you see on Amazon/Ebay. Many others have used these with success but I had a real challenge getting a good crimp on 4/0 cable. Part of the issue is that they are sized differently and so all the dies are either too big or small for various wire. I mention this because I ended up purchasing a Temco Dieless Lug Crimper that is similar to a hammer crimp but easier to use. It is not as pretty of a crimp but the crimps are very solid and it is much easier to use. Unfortunately, I am now the happy owner of two crimpers. The one that has worked very well for me is in the following link. I have no affiliation or amazon kick back account but thought I would share so others don't make the same mistake.

Also, be sure to get wire cutters that are made to cut 4/0 cable. There are some with longer handles or ratchet style but be sure to invest in a good pair of wire cutters! These are the ones I have used that have worked great but I know the ratchet style would also work good.

The Endoscope I mentioned in another post was also really helpful in figuring out how to fish the wire to the roof. You will also need a good hole saw cutter set. Multimeter can just be basic but necessary to check your wiring and panels as you go along hooking everything up. I also ended up using a small dremel and oscillating saw from Harbor Freight which was handy to have. You will also need a smaller crimper for the smaller wire crimps. If I think of anything else I will mention it.Damon and Colleen

If you can return it easily I probably would. That is the same crimper set I originally bought. I only used it to make the battery cables and was very challenging for me to get a good crimp. The first ones I could pull off and finally used a smaller die than recommended and did 2-3 crimps rotating the cable to finally get a crimp that I felt was adequate. However, it was a lot of work and ended up with a blister on my hand. I certainly could also be doing something wrong. The second one I bought (in link above) was much easier to use and you don't have to fumble with various dies. It has an adjustment to move the barrel for various lug sizes. It will also hold the lug when you set it in and can push the wire into the lug to get a tight fit before crimping down. It was much easier for me to use and provided a good crimp that felt very solid. I may end up redoing my battery cables at some point with this crimper but I think they are good for now.
The wire cutters above should be great and better than what I used. If I was buying wire cutters again I probably would go for the ratchet style like what you bought. I also looked on Amazon and it looks like in the reviews others have used them for 4/0 cable with good success so you should be good!Damon and Colleen

Ratcheting cutter will for sure work. I've used that type on thick gauge cable.
For the welding cable, no problem. I use a Greenlee 727, 4/0 is a bit big for it. If it didn't I'd break out a ratcheting cutter.
Crimper, I use a style that looks like it puts the same crimp on the lug.
They're Greenlee KC4-4/0 https://www.greenlee.com/us/en/die-s...cu-awg-kc4-4-0
I start crimping the lug end where the cable end is and put down 3 crimps one next to another till get to the other end of lug where cable enters the lug.
KC4-4/0:

Couple of picts with a 4/0 lug already crimped. On mine, I crimp with the flat of the lug away fm base of the jaws so it clears them. Smaller lugs usually not an issue.
So good to check if the lug's flat clears the crimper's jaws.
A 4/0 Lug with flat toward base of jaws won't clear the jaw's opening.

Looks like Gene is using a very expensive Greenlee crimper that provides a calibrated crimp. These tools are made for the trade and don't come cheap. This one is maybe $1500+. Been retired for a few years but I recognize a trade tool when I see it. Greenlee is top notch stuff.

The trick for fine stranded welding cable is multiple crimps with these types of dies to prevent pull out.
That's not much of an issue with the heavier stranded building type wire like THHN/THWN
Sometimes with the fine stranded welding cable a hammer crimper can work as well or better.- Gene
