Adding extra fuse circuits
I've ended up with a spaghetti mess of added wires on my positive battery terminal with the various electrical add-ons... They are all individually in line fused but it seems it would be cleaner to add another fuse block somewhere....
I can't find a spot in the frunk to put one though.. any suggestions? |

The size of the new fuse block depends on the number of extra circuits, of course. The fuses are to protect the wires, so I would place the added fuse block close to the original one. There are many different fuse block configurations available. I have used the Blue Sea Systems blocks and like them a lot:

Yes, but where did you mount it
 Looking for possible suggestions on a usable space.. there just isn't much room left in the trunk..

I have been working on this for a while.
Cardboard model of Blue Sea 5028 and 5046  5046 fits nicely.below the factory fuse box.  Prep for install  Bonded studs on. Did not want to drill into the wheel well.  Getting the cover on and off with fuses is tight, but it fits.

Now I needed to find an open space near the fuses for some relays.
The strut bar provides a convenient mounting location for a row of relays. I bought a pack of 10 Bosch 3334485008 relay bases, they slot together nicely.  Hose clamps are just for the test fit, I ordered some 7/8" dia split collars that will hold this securely.  Still a work in progress.  I needed to add fuses and relays for the oil cooler fan, air horns, and for a set of hood mounted driving lights. Figured I would go ahead and add extra relay slots for future expansion.

I like the one reclino showed above - still seems pretty tight space to get that block in there.. especially with the headlight relays already mounted nearby.. I'll just have to keep searching for the right size that fits in what little space is left
