Can someone help design a 5 volt circuit
Yes I realize this is an RV forum but the post is related to wiring on my tow vehicle. I have a diagram below of what I am trying to do. But I will spell it out as best as I can first. My hope is that...

A return is generally the negative terminal of the power source, not where power goes into something, so I’m not sure what you are trying to accomplish.
If you need to feed the 5V out to what you have labelled 5V return ( which I would not do unless you are certain that’s how it works) just put a switch between them and turn it on when you need it.
For the circuit you have drawn to work, the 5V return would need to be the negative output of the 5V supply, but your circuit won’t do anything. Since you have no info about the rated power output of the computer or the coil resistance of the relay, it might burn up the computer
