He was just having trouble with the neutral safety switch. I don't remember where the switch is located but I think it's under the shifter console, just use the starter side of the switch and you'll be all set. I am guessing that you ran a wire outside the car to test at the solenoid.
The tach wire is Green with a Yellow stripe it's the #1 wire on the right side harness on the inst. cluster.
The 2015 is a nice alarm you'll like it. If you have 2 cars, 1 remote for both cars is a cool option. I have the 2011 in my SC (it's a 5speed)
I have to call them about a customer’s alarm that is giving me fits.
All cars are easy to steal.
If you were speaking of the fuel shutoff (inertia switch) that is in the trunk, no one really has a problem with them.
If you are talking about adding a relay for a shutoff then I would wire it normally open that way even if the alarm is disabled the relay won't function. If the relay contacts go bad then all you have to do is move the wire on 87 to 87a and that circuit will function again even if the contacts for the normally open side are burnt. (they are separate contacts)
I have a CS-9228 Vector on another car. It is the only line that had a normally open starter kill. It's been on the car for about 6 years without a hitch. Then again I have had relay's switching less than 200ma go out in a few weeks. Always buy quality relays like Bosch or P&B.

BTW they don't tell you about the 2011 and 2015 being able to do manual cars, but it's built in. You just have to cut a trace on the board.
