Stop in for a cup of coffee

Morning!
Forgot my usual intro…
Sunny, warm and almost no wind. First thing out the door was fix a couple loose shingles on my lil garage/office/man cave.
Now on to prepping wire harness to go back into the 37. Some wires are a little short, will deal with that as needed.
Line lock, looking for advice. Or in this case, opinions.
Its plumbed to hold front brakes. So a single push button to energize solenoid?or a dash mounted rocker? This car is a toy, never going to see the strip. Owner just wants to burn some expensive rubber..
I would use a push button that has to be held, then let go of button to release the brakes
