Now own to electrical it really wasn't that bad and I'm going to give you all the info. SEE PICS
First off the neutral safety switch. I just cut the cable after the plug (cut by the sensor) that way I still had the plug on my car and could always buy a new sensor. Then you just put the wires together. To test this you can take you sensor wires with a volt meter and check the ohms with it in neutral and in gear. it will test ohms in neutral. thats the way you want it all the time like it is in neutral so the wires go together. zips tie it out of the way or if you really want to clean it up and don't mind pulling the carpet up you could pull carpet find wires cut and tie together and hide under carpet.
Now for the back up lights is simple cut the sensor side tie in with your new pigtail you bought plug into new style sensor and you are done.
Now the reverse lockout this also ended up being easy. (See pics for help) They say its 2.5x2.5 but its 1inx1in
I just ran it behind the radio.
You have 4 wires https://img1.wsimg.com/blobby/go/197...h40_640512.pdf
Ground Black (Just ground it)
power to reverse lockout and Unit Red (Need key on 12 volts)
ground to reverse lockout White
remote wire to VSS. Blue (This will work with your stock VSS I did it on the +side but they say it doesn't matter)(See pic)
I pulled carpet and tied into the VSS inside the car. I also plugged the 2 wires I needed outside through the rubber plug that the transmission wires came through the car so it was super clean. those 2 wire go to the reverse lockout.
