How to wire a power distribution relay block to a automotive negative trigger / switch kinda of!!!!

Hey guys just my take on how to wire a negative relay switch / trigger. I m building a power distribution relay block but my trigger / switches in the cab will be negative switches to activate, so instead of 2 positive wire per switch I only need one negative/ ground wire per switch, and sense I have 5 switches that I want to use I only have to run 5 wires through the fire wall not 10, and that there are ground wires so I don't have to worry about possible shorting out and causing a fire in the cab and of course I am running fuses to everything. Hope this help, if anybody has any questions plz comment. This is for educational purpose only I am not held liable for anything that you do.
