Ran into a predicament while wiring cathodes

[Nexus1155]

Ok so I wired them up pretty well... got the grounds and powers running under the carpet to the center box, and tied together, ground is ringed around a bolt under there...

I have a 3 way switch i bought and i tied the power from the transformers to the middle terminal on the switch which is usually for the components...

I then proceeded to snake the wires up through the carpet under the pedals and into the fuse box... this is where i am at now.

I wired up a 3 Amp fuse to both of the power wires i was about to hook up

I tapped into the pink Dome wire for Dome light power so whenever the door is on the lights would come on too... and then i looked for a power source but said hey before i do that why not try it out... switched the switch... nothing at all... then i was like damn this sucks and tried every combination possible on the switch to see if i messed up the wiring...

I was looking for a constant 12v but dont want to keep poking wires until i get lucky if anyone knows of any down there... Thanks for all the help!
