Carson Reflex Wheel Pro 3 Cover Plate

Since the receiver of my 2-channel remote control has 4 channels, I thought I'd check if the remote actually had 4 channels and they were simply unwired. And sure enough, I found the two missing ones. Channel 3 works, and to use it, I connected it to a potentiometer and can now control the lights on my car. I don't know if this works with all Carson Reflex Wheels (mine is quite old). It's not a perfect fit, but it's sufficient for me.
