I finally had a chance to sit down and work through a relay design to control the Reverse flood light setup I want for my truck and RV.
My preference is to provide a solution to enable/disable the lights to work automatically with the Reverse selector, a means to disable that, and also to provide a forced ON switching ability. The reverse trigger is the one available in the 7-pin trailer connector. I plan to split this out to use it for control of both the truck reverse flood lights and the RV flood lights. The power to the trailer lights will be supplied through a truck mounted relay, but I'll also install a simple SPST switch on the RV to run them independently. I'm assuming a load is already present in the RV charge system that is fed by pin #4 so hopefully my design won't be at odds with that.
I'd appreciate any input on the solution below before I get busy building it. I used an online circuit sim tool to ensure I wasn't going to smoke anything and it all should work without relays sticking or bouncing, so please excuse the relay representations as it's the best I could do with this particular (free) sim's layout capability. I did label each coil and power lead used.
Short of building some crazy gated circuit, this is the best I could come up with although it uses up the 4 remaining AUX switches. If there's any electrical engineers that see a better way to do this, I'm all ears.
Here's an image shot of the circuits:
If anyone want's to check it out, play with it, or make changes, here's the link to the online sim and the latest file.
Aux2 and Aux4 supply power to enable the LED's to come on when the truck is put into Reverse.
Aux1 and Aux 3 Allow manual control to the Floods.
Any/all switches can be toggled to any position without concern for letting out any magic smoke.
Diodes are 1N4001. LED's represented are as close as I can come to the "KC HiLiTES (332) C3F 3" 12W LED Flood Beam System" I ordered.
