b2200 transmission sensors??

there are two plugs/ sensor in my tranny ...im almost positive the one on the drivers side is the back up lamps but not exactly sure about the other... it went to the abs shit that i eliminated.. do i need it? and does anyine know where the second wire in the reverse plus goes? mine dead ended...lol

or is it this? wtf is a neutral switch and what does it do?lol

A neutral safety switch prevents a vehicle with an automatic transmission from starting unless the transmission is in Park or Neutral.

my truck is 5 speed so i guess thats not what i have..lol. any clue as to what they are? trying to wrap this wire tuck up ...lol

What year is your truck, and is it EFI? I have a 93 with EFI, and I have a sensor on the tailshaft of my tranny, it tells the computer on the truck if the shifter is in neutral or not, it bumps the engine idle by 100RPM or so when the truck is in any gear, must be some sort of anti stall feature. I can still start my truck in any gear, as long as the clutch is pushed in.
