Dimmer wall switch for interior LED lights?
I just switched my old tube florescent lights out with dim-able LED strips. I bought a DC dimmer wall switch for the lights but it had 4 wires and there was no way to install into my 2 wire system. ...

There are a bunch of them on eBay. Just search for RV led dimmer.
2 Wires?
Not so sure about that unless they are nothing more than a variable resistor.
DC electronics will need at least THREE WIRES in order to work.
Input + from battery
Battery "ground" (-)
Output + (variable 12V DC) to lights
Since OP has only 2 wires to work with they will most likely have to run a battery "ground" (-) to the switch location.
I suspect that the OPs wiring is only Battery + and the switched + that returns to the light fixture and no battery (-) to be had...
They're not just pots and they don't need three wires if they have full 12v coming in because they use that to power an appropriate circuit.
Here are examples:
Simple surface mount
Wall mount led dimmer
I have both of these.
