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. ...

AH HA!!! So....
I DO see some DC wires running a few feet under the light switch (going to the LP sensor). If I wire into THAT ground wire, should it work? Or do I need the EXACT ground wire that runs to the lights?
And I have 2 wires for (ground) on the switch. Should I put them BOTH to the ground? Or only one? and what one? IN or OUT? :)
The wrinkle to that plan maybe as DrewE pointed out..
Some of those dimmers actually pass the pos lead at full voltage and reduce the ground lead (IE "lift" the ground potential).
That type of dimmer using only one ground lead will not work and you would need to have 4 leads, two from the battery pos and neg plus two going to the light pos and neg.
Won't know which one you have until you try it.
