I am looking to install a few mini rocker switches and a pac lc-1 RCA knob into the waterfall or possibly in the little pocket next to the shifter (not the big one, the one that is long and skinny)

The pac lc-1 can be taken apart and the "bolt" for it is not very thick.

I don't have the fog lights and I don't think I will ever get them

Any thoughts on placement of these?

As you can see, my dash area is pretty messed up because I have 2 rocker switches and the pac lc-1 I need to mount somewhere for my amps and line output converter

I've circled in yellow the storage space I am talking about. I thought about getting a piece of plastic or metal to insert there (I think it would fit perfectly over the small edge it has) and then drill a small hole or 2 under it to feed the wires (much better than cutting the interior up like that)

Any place that they will be secure and easy to get to is fine. Even if they are hidden.
