Default interior power supply and switches (parralel circuit)

Hey guys, I said earlier Id do a write up about how i ran a power supply to my switches in my car. I did it over a period of time so some pictures are missing but maybe this can give people some ideas.

ok so the first thing i did was find a place to push the wires through the power wall. The gromet where i believe the heating control run through provided my entry into the cabin.
here you can see the red wire
I taped it to a coat hanger and pushed it through, I had to have my buddy push it and then feel for where it came through, its possible to get it through without cutting but i was to lazy to do that much work.
Then to get the other wire through you just tape it to the other one and pull it.
sorry for the bluriness, phone was hit and miss that day. This is where the wire ran through in the cabin.

Next i crimped in a in line fuse, you want to fuse for what the wire is capable of handeling. I used 12 gauge and a 30 Amp fuse.
then i connected ring terminals to the hot and ground wires (and electric taped of course)
I connected the hot wire to the aux battery terminal
the wire routing (once again blurry)
you cant see it but i grounded it to the bolts on the strut brackets.

Next I made my wiring harness (the three way spliter)
I used some quick disconects i had laying around and small ring terminals and nuts/bolts.
Then i simply crimped in the rest of the QD's
of course electric tape all hot conections and grounds before a load.

This isnt what i ended up using ( made it smaller) But i insulated between the splitters with a small piece of styrafoam and mounted it in the center console with velcro, but you get the idea.

Beacuse the switches have their own ground and a B+ i had to make some creative wiring harnesses for them.
I used flat spade connectors so i could easily connect the sources later
For anything that was connecting to the terminals on the switches i used standard spade connectors

I drilled holes for the swtiches and mounted them on the center console
This is where put the QD's
the splitter mounted under the center console plate
the wires connected under the dash area
and what they look like mounted

Ill try and take some pictures that are obviouslt missing when i take it apart again to install my LED's

The point of a parralel circuit is to divide the amperage between the circuits while maintaining a constant voltage, also if one circuit goes out the rest stay working. Which is pretty obvious i guess. Sorry im not very good at explaining things but if anyone has questions I can answer them.
