2000 silverado Holley terminator integration On my 00 silverado we just installed Holley. I was originally gonna integrate the original OEM harness into the Holley. But Imma run a Holley dash since I have one and just do away with the OEM stuff. Pretty straight forward and simple to do. Only issue is trying to get the starter circuit to work. I can do a simple push button start if need be. would rather have it off the key. I seen a video about the "crank" fuse being hot while starting only inside the interior fuse box. Thought about running a relay and using tht fuse as ignition. Has anyone done anything similar?
I will know tom if tht fuse will stay hot while cranking. Figured it should be. Only stuff we removed was the ECU and harness. Will this relay also need a large fuse similar to what the OEM had? Or a simple 10 amp on the relay ignition side suffice?

I'd do exactly what you're talking about. If that CRANK fuse gets 12v only when the key is in the START position, I'd tie into that wire and use it to trigger a relay. Leave the fuse and wiring alone, just tap into it and run that signal to pin 86 on the relay, ground pin 85, run a fused battery feed to pin 30, and run pin 87 to the S terminal on the starter. That way when you turn the key to START, the CRANK circuit energizes the relay and the relay sends power to the starter.
