I searched for this couldnt find one that helps me with how i want to do it. I am wring in a push button to activate the starter only the key only goes to the on spot and wont activate the starter so i want to use the pushbutton what wires do i need to use to acheive this my wiring diagrams suck!! I am working on an 88 cherokee laredo

 

Check the tech writeups. There are a few ways of doing it. Can you jump the starter solenoid to start it?

 

If I jump the starter it starts I just don't want to do that everytime the key powers it all up but the start part of the switch is broken

 

Ok found what I needed but my harness Dosent look like his is this my yellow I need and the red I need ?
