Installing an electric fuel pump along the frame. Is there a good keyed 12v I can tap into for a relay down there or am I running wires back up to the engine bay?

Keyed 12v along chassis

Not a clean 12v ignition source unless you have TBI wiring and want to use that.
I don’t have a TBI.
On a square body ?..
There is a keyed 12V wire on the fuel tank sending unit,but I'd avoid tapping into that one,it'll likely affect the gauge readings and the fuse & wire probably isn't gonna like having more load on it..
I'd run a new wire to the fuse box and install an inline fuse,however the fuse box may have a keyed 12V "ACC" tap,but be sure it only gets power with the key in the "ON" position,not on "Accessory"--otherwise the pump will be running when your sitting there listening to the radio with the engine off..

run some wire and your better off keeping the relay under the hood anyway.
I was just trying to be lazy. Oh well. Worth a shot. Thanks y’all.
