Wiring diagram review for rear Aux LEDs

Can someone review my diagram for my rear aux leds? I have to order 2x flushmount LEDs to install in my rrar bumper. I am trying to figure out how to wire them. I have the following conditions:

1- Turn on/off from I side the cab
2- Turn on/off from the rear
3- Turn on/off automatically with reverse lights
3b- this leads me to wonder whether reverse lights are positive or negatively switched? I was assuming positive when I drew this up.

I understand basic circuits, but relays etc are fairly new to me.

Is therr a simpler way to do this?

Thanks

 

subd. I would like to do the same type of set up in the near future. Were you able to get everything worked out?

 

Sort of.. lol. I installed these in the bumper, sorry for the crappy phone pic:



I got this wired up in the overhead console:






And I have this preped to go in the bed under the canopy:



I have pretty much all the wires run for the rear, just have to start terminating everything. Might be a week or so as I am waiting on a small piece to come in the mail.

 

It may be just me but it looks in the drawing that you are switching the negative side of the circuit.

You can do this more easily while using just 1 relay but you will have to incorporate a diode or two to prevent current back flow to the factory reverse lights.

 

Yes, intentionally switching negative. Wpuld rather run switched negative along the frame rail than positive imo.

Curious to see your 1 relay method?

 

This is a post I made awhile back in this thread;

Not exactly what you want, but it could be modified to what you want.

I'm very interested in what dual battery system you have and where you got that digital voltage gauge, is that aux battery switch being used to change which battery is being read by the meter, or is it a disconnect switch for the systems that are powered by the 2nd battery?

 

Thanks for the diagram. I have pretty much resigned to the negative switching, dual relay setup at this point. I have run wire to the bed of the truck, just need to fab a mount for the switch bezel & some aux power ports for fridge.



As far as switches go, here is a better picture. The red switch on the left allows me to Connect or Isolate the batteries manually, or have the Bluesea 7622 combine/isolate automatically when charging voltage is sensed (connects about 30 seconds after starting) leds indicate when batteries are connected.

The Aux battery rocker switch chooses whether starting or aux battery voltage is displayed on the volt meter, or shuts the monitor off all together. Voltage meter comes on with ACC.

The small momentary switch below the v meter temporarily powers the v meter to check voltages while ACC is off.
