How can i rig up a remote start switch in the kj like mechanics use to start a vehicle? Note: I am not talking about wireless remote starter.

You can rig one to crank the engine since the starter has only 1 wire but I'd not want to start it taht way since many things need to get power also to start and stay running.

If i had the key in the 'on' position and cranked the starter with the switch would that work?

That would work.

ok thanks. And one more question. How would i shut off the engine without turning the key?

You need to tap into the Auto Shut Down relay to do that,it cuts power to the injectors and fuel pump.

aha, i will have to look at that in the service manual. thanks.
