I am finishing up a complete rewire of my 28 PU with a harness kit. I wired the electric fuel pump through a relay to the designated wire to the fuse block, plus a wire to a "12volt battery constant with a inline fuse". To me this means to my battery.
Well, of course, when the battery is connected the fuel pump runs even though the ignition is off.
Where am I going wrong. I know I'll want to give myself a head slap when I get the answer. But I'm stuck. And, yes, there is a good ground to the chassis and hot lead to the pump
Can someone give this rookie electrician some help?
