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...

I will simply echo the above. Without knowing the capabilities of the 5 v out and 5 v return and the intended design function of those there is a definite risk to your computer in connecting anything to those points. I would be surprised if it could provide enough current to energize a relay of any size.
