I need a wiring diagram that shows the color coded & or pin location of the neutral safety switch wires where the harness plugs into the transmission on a 2005 Pontiac Grand Prix. I don't know wh

I need to know which color coded wires are for the Neutral Safety Switch on my 2005 Pontiac Grand Prix. It looks like the switch is INSIDE the transmission. I'm guessing they started doing this around 2000, judging from the GM front wheel drive cars I've seen in the junkyard. There is one 'pigtail' of wires that plug into the bellhousing on top of the transmission. If anyone knows of any other GM cars that used the same transmission wiring harness as this, then I would greatly appreciate any information you could give. Thank you.

Which two prongs to connect to bypass neutral safety switch on 96 Chevy

The neutral safety switch is an important component that prevents the engine from starting unless the transmission is in the neutral or park position. If you no longer have the switch, you can bypass it by jumping the starter relay. This can be done by connecting the two wires that would normally go to the switch directly to each other.
Here's how to do it:
  1. Locate the starter relay in the underhood fuse box or the power distribution center.
  2. Find the two wires that would normally go to the neutral safety switch. These wires are usually color-coded and easily recognizable.
  3. Using a jumper wire, connect the two wires directly to each other.
  4. Turn the key to the "on" position and see if the engine cranks.
Note: Bypassing the neutral safety switch can be dangerous as it eliminates an important safety feature. It's also ******* in some states and can void the warranty on your vehicle. Consider using the bypass as a temporary solution until you can obtain and install a new neutral safety switch.
