im thinking about putting a push button in my 1999 f150 xlt so that i put the key in, turn the key to start or run, but it will only start if i push the button no matter how far i turn the key. in the install manual for the push button it shows that i need to connect the push button wires to the old ignition wires, and i was wondering if anybody knew what the ST, IG, and +B wires look like, as those are the ones it shows i need to connect them too. i can attach the picture if it would help. Thanks
