Need to know where to find a complete wiring kit one I am working on as soon as you touch the + cable it try’s to crank even when kill switch is engaged any suggestions and help is appreciated

 

Kill switch is to kill the spark, sometimes also stops the starter circuit, but often doesn't. If the starter turns when the ignition switch is off however, the solenoid has stuck. Buy a new one, but check the battery, as a flat or weak battery can cause the solenoid to engage slowly which makes it arc inside, and stick. If the starter doesn't run until you switch ignition on, either the start button has stuck or there is a wiring fault in that circuit.
