The relay is so I have a reading from the battery and not the keyed source. The keyed source acts as a switch to interrupt the power from the battery. Not sure if that makes sense.
Don't forget to photograph the install and post it here.
I'm interested to know why you think a relay is needed - if you are going to find a keyed source ???
And yes you can add a switch later - but then you would have to open it all up again.
That's one reason I did the switch with the meter install - maybe I will never turn it off - but I can if I want to.
Looking forward to your version of a volt meter install
