I have a 2008 F250TXR I did work on and I'd like to start it on the hose. I do not have access to the boat / remote so I'm looking for the best way to test it. I have the service manual and see where the starter relay is but seems like I would also need to supply 12v to the 'run' wire aka the wire that will shut it off. Please see attached .. I'm thinking the 'Ian switch 12V+ is what I'd need to feed 12V for it to run and maybe that engine stop wire is the lanyard?? Of course the large battery wires themselves will be connected on the engine directly. Any thoughts?? thanks
