If you're a keep it simple sort, I'd avoid the start switch override altogether. Simpler to wire in the first place, simpler to troubleshoot later.
I have a manual button for the override. If I have run the fuel out after shutdown, I use it. If the engine was just turned off still showing fuel pressure, it is not needed.
