2007 mustang neutral safety sw?

Sister has a 2007 Mustang GT manual. She wants a remote start. In the past, I have been okay with the idea of just using the E-brake switch instead, so that it will only attempt this with the E-brake on. My reasoning was that if she did leave it in gear, she'd at least have to have the E-brake on, which should cause the car to not start or to start and immediately stall instead of moving. However, I did read this: www.autoblog.com/2010/03/25/forum-fodder-dealer-accidentally-remote-starts-customers-musta/ They claim the E-brake WAS on and the car still moved. They likely didn't pull the E-brake up all the way, but if they did that, then the same thing can obviously happen to my sister. So I most definitely do need some sort of neutral safety switch. The car does not have one stock. Has anyone ever added a neutral safety switch to a manual car? I would like to add a neutral safety switch, and then I would use BOTH the NSS AND the E-brake switch, making sure the car is in neutral AND the E-brake is on in order for the remote starter to work.

You should buy a remote starter that is made strictly for manual trans. CompuStar makes a good one that you have to do a sequence to make sure the car don't start in gearConfidence is the key to any project!!

Never known an ebrake to be safe, think parked downhill in say San Francisco, it wouldn't stall out, it would just keep going. You MUST install a manual safe R/S.
