Manual Remote Start Safety Module

This is a great idea there man,But remember this setup wont last long,due to the fact the friction overcome everything.Endless spring breaks.Did you know that shifting gears from 1 to 5 Is a lot of strain on the setup you have.My uncle said to me use a 12v lazer set up across the gearstick.When the lazer light brakes,power will be restored to the relay to work the remote start.

If you do use a lazer you would actually need to put two sets so that the signal will break if it's in gear right.  If you only have one to detect if there's an obstruction by the shifter in neutral it could be a problem if something else got in the way like trash or a bad lazer right.  Have you looked into this?  I wonder how reliable and expencive they can be.Poly Dollies

We'll just have to find out, won't we?!

The gear shift lever isn't grounded because the factory isolates it from the surrounding metal (transmission, floor pan, etc.) with rubber or teflon insulators so vibration and road noise isn't transmitted up the shifter and into the car.  Another reason they do this is to minumize wear on the hard parts (the ball on the end of the shifter lever and the receiving "cup" in transmission).  If you've ever driven an old Toyota pickup truck you probably have noticed the shifter has a LOT of play.  This is mostly due to the teflon insulator being worn out, replacement will almost perfectly restore shifter feel.  Theres no special voodoo reason the shifter isn't grounded, its just not grounded as a by-product of design.

small lazer under the gearstick boot will do the trick but you are right,it is expensive.I know of spy shops selling those in my country

Its in the gearbox comin from the factory
