Hey guys i really want to make a Engine Start Button for my Ef

in theory it should not be that hard as the ignition barrel should basically just complete a circuit when its clicked onto start, has anyone done this before and if so how did they do it.

Just want it so i put key in click to last click b4 start and then press a button,

Any help or idea's would be great thanks

ftg used to sell complete plug n play starter buttons for e series, not sure if they still do or not.
