My ignition shaft behind lock cylinder broke. I decided to buy a push button start instead of a 260 dollar housing. My key turns enough to power my accessories. I got the push button start in. It's cranks but won't start. I turned my radio off and listened to see if my fuel pump comes on. It is not. I want to wire a toggle switch to my fuel pump from the back of the ignition switch. I need to know which wire it is. I can't download wiring diagrams on my iPhone so I can't see them.
