So this week I pulled at a thread and ended up getting a good bit of work done.   I got a small relay/fuse box from Amazon and was able to get it mounted and wired.    As per my previous post I installed a pair of 120 DB air horns.  I am not sure about the town you live in, but traffic here in Toronto is hand to hand combat at best.  If you can't be seen, you can be heard. 

The horns require a dedicated relay and the LED headlight harness requires a dedicated relay for each light.  I am not sure why, but after I started stripping the actual wires they were at best 18ga, maybe 20ga.  So after i took a look at the way they were wired, I decided to reproduce the wiring in 16ga, just to future proof the system in case I wanted to back to incandescent later. 

Once I got the hang of the new pliers and the connectors it went fairly smoothly.   I specifically wired the relay box so that it could be rotated up for any future additions.   It has space for a heavy duty relay that would be ideal for an electric cooling fan, it also has space for a regular relay that I will likely use for the pusher fan that is installed for the A/C.  The part that I don't understand is the box came with only half the fuse connectors I need to fill the box, and considering I messed up a couple it left me short.  Luckily i ordered a few in case this happened. 

The size and fit of the relay box seems to work very well in the space.  I am cleaning up a 3d printer file so that you can print a mount for the box.  I really like the fit and I am confident that it can sneak around the battery. 

I also installed the positive rail, an 80 amp circuit breaker and two 30amp self resetting circuit breakers, one of which I am feeding the balance of the car with, the other for a spare/fan circuit breaker. 

It is not super sano, but it is as tidy as I can make it without building one from scratch.   The wires can be traced, easily troubleshooted, correctly fused and weatherproofed. 

I will be securing the main feed positive wire, the main ground cable. Hopefully I can find some time tomorrow to get it done. 

P.S the green wire will get pulled out and the ground wire is there just in case I need it for the relay box.
