I've recently acquired a 2017 ZL1 and am looking to install a fuel pump kill switch. While looking through the threads here, I've tried to identify which wire would work as a kill switch and so far I've yet to get one to stick.
So I followed this thread:

And it still starts right up. There was a smaller (20 gauge) that appeared to also be green and grey. This one disabled one of the sensors up front so that wasn't it (I've now repaired this one).
The 2022 and 2017 electrical schematics for the ZL1 look similar enough in regards to the fuel pump relay.
At this point I'm wondering if I'm just out of my depth or if there is some redundancy I'm just not taking into account.
