Where is the Fuel pump wire?
I want to hook up a fuel cut off switch for my C5 z06 and run it underneath the shifter boot in my ride. Where is the hotwire for the fuel line? What color? etc.
Thanks!

Probably better to cut the relay B+ feed wire (smaller gauge wire and far less current than than the fuel pump wire itself). The feed wire cut / switch would stop the fuel pump relay from energizing, and therefore no fuel pump juice.
You can gain access to it at the underhood fuse block. Have to disconnect the battery, and then remove the 2 nuts holding the fuse block down. I use a battery tender type charger in my cigar lighter to keep the memories. Once the fuse block has been unbolted, find the C1 (large black plug) wiring plug and then find wire E12. Will be a .35 Dark Green / White wire. Cut that and run it to your cutoff switch. That is the wiring on a 2003 (I hope yours is the same)
Good luck,
