Hot wire when ignition is on under hood?
Installing an electric fuel pump and i want it to come on when my ignition is on only, is there a wire somewhere under the hood i can splice into or do i have to go into the actual ignition switch?

Ignition unfused on the fuse box. I'd run a relay though.

Don't be in a hurry. Do it right. The fuse box is located under the dash on the far left of the driver's side.

Re: Hot wire when ignition is on under hood?
I found the unfused fusebox spot having too much there already. And used one off the ignition switch. When you start adding HEI, headlight mods, door poppers, electric antenna, electric choke, dual fans, and electric fuel pump among more stuff managing safe places to tap in becomes a challenge.
