Well I did this so I would be assured of my remote start system to not start up when I'm in gear.. and also I set up a led to light up when I would shift into gears.. If u have basic knowledge of relays and wires it should be easy.. I got the parts from radio shack and got some double sided tape from the 99 cents store.. So I could mount the magnets onto the shifter plate when I had it aligned properly.. It took a while to test and get it right, my test procedure was after I got the reed relay on the shift adjustment bolt with electrical tape I started placing magnets on the shifter assembly and hooked up the reed relay to a power source and a led so I could tell when there was contact, I would test it by going into each gear and then test the gates of each gear making sure if I pushed it into one side in gear it will still know it was still in gear, then next moving into neutral, and over and over to make sure.. I found out that I needed to mount two magnets on the right side of the shifter assembly because when u would go into second gear the right shift connector would hit the magnet and messing up the alignment.. The write up below displays my results of my magnet placement and is now in perfect working order.. But every time before I leave my car I double check the shifting process making sure it detects if it is in gear or not, just in case I decide to remote start it.

The reed relay is basically a magnetic switch, when a magnet is near the side of the relay it connects the electrical points together and completing the circuit, then when the magnet is moved away the points disconnect, this same switch can be found in home alarm systems, where there are opening window detectors.
I forgot which reed relay is required I will get the part number from home later on, but I don't think the amp would matter since it is running very low voltage.

It would be great if some u guys can post this on your sites.. and I would appreciate
it if u guys still give me the credit into doing this...
I will have a write up soon on what to do to connect this up to your remote start system and I will have better pix soon.
