On GM's if you pull the
On GM's if you pull the connector that is in line with the hood latch sensor, it disables STOP/START. System logic shuts off stop/start if the hood is open, so you "trick" it. The only downside is the check engine light stays on. Minor inconvenience. When you go to dealer for service, reconnect the connector and no one's the wiser.
The aftermarket modules plug inline on that wire harness and do exactly what pulling it does, except they also turn off the check engine light. That benefit cosses you about $150 bucks for the module.
