I'm putting my 2007 Mazda 3 hatchback 2.3L into storage for 6 months and am following this checklist:

http://www.techguys.ca/howto/winter.html

they mention disconnecting the fuel pump wiring harness to remove pressure in the lines and I'm not sure where it is/which wire of the harness to disconnect? When I look it up I keep finding wiring diagrams, but I'm looking instead for the physical location on the car?

Thanks!

If you're that concerned, I'd unbolt the fuel rail, remove then injectors and empty the fuel rail. Should only take 20 mins. At least you won't get varnish building up once the fuel goes sour!

Easier solution; run the car and pull the fuel pump relay; it'll depressurize as it dies.
