LC-50 and G3X + LED Strip Dimming Question

[Craw]

Gooday All,
I am doing my best to put together a wiring diagram for the LC-50 Lighting controller:

(https://static1.squarespace.com/static/5282b286e4b01dd0edf58599/t/5343f341e4b0f92a7a690686/1396962113578/LC_50_Manual.pdf

wired to dim various Garmin LRUs as well as two of these LED strips (dual white/red):

The idea being to have a total of 2 dimmer knobs: 1 dimmer to control the Garmin LRUs and a second dimmer for the two LED strips (1x in the Glareshield and the other in the footwell of an RV-7A).

Lastly, I would also like the LED strips to be controlled by a three position (on-off-on) DPDT switch, one position for red LED lights, Off position and one position for white LED lights.

I have uploaded the draft diagram I have been working on but got stuck at the DPDT switch and LED strips. Could one of you help me complete the drawing and confirm the elements already shown are correctly wired.

Thanks in advance for your support.

From the LC50: out3 to switch pin 3, out4 to switch pin 4.
From led1: red to switch 1, white to switch 5
From led2: red to switch 2, white to switch 6
Both black led wires to ground.
Use reds to pins 5 and 6, whites to 1 and 2 if you find the switch is upside down (whether you want red up or white up).
You understand that the LC50 is gross overkill here? All these circuits/LEDs are very low power, a simple linear voltage regulator ($1.) would suffice.

Thanks for the quick reply, and I was not aware of any other way to wire this. It would be great if you could provide me with a drawing or reference to other cheaper alternatives that achieve the same function with two dimmer knobs.

Thanks again!

Google “lm317” and “adjustable voltage regulator” and you’ll find some simple circuits.
