When restoring a classic 1965 Mustang, one of the many things that need to be checked and possibly replaced is the neutral safety switch. The neutral safety switch is an important component that ensures the car can only be started in the “Park” or “Neutral” position. In this article, we will provide a detailed guide on the wiring diagram of the 1965 Mustang neutral safety switch.
What is a Neutral Safety Switch?
A neutral safety switch is a safety device that prevents the engine from starting unless the automatic transmission is in park or neutral. It is also known as a gear position switch or transmission range sensor. The neutral safety switch is designed to prevent the engine from starting while the car is in gear, which could result in the car moving unexpectedly and causing an accident.
On a 1965 Mustang, the neutral safety switch is located on the automatic transmission shifter assembly. When the shifter is in the “Park” or “Neutral” position, the switch is closed, allowing the starter to engage when the ignition key is turned. When the shifter is in any other position, the switch is open, preventing the starter from engaging.
The Wiring Diagram
The wiring diagram for the neutral safety switch on a 1965 Mustang is fairly straightforward. There are two wires that need to be connected to the switch – a green wire and a pink wire. The green wire comes from the ignition switch, and the pink wire goes to the starter solenoid.
The green wire is connected to one of the terminals of the switch. The other terminal of the switch is connected to the pink wire, which goes to the starter solenoid. When the switch is closed, the green wire is connected to the pink wire, allowing current to flow from the ignition switch to the starter solenoid, which engages the starter motor and starts the engine.

FAQ
Q: Why is the neutral safety switch important?
A: The neutral safety switch is important because it prevents the engine from starting unless the automatic transmission is in park or neutral. This helps to prevent accidents and damage to the car.
Q: What happens if the neutral safety switch fails?
A: If the neutral safety switch fails, the engine may not start or may start in gear, which could cause the car to move unexpectedly and cause an accident. It is important to replace a faulty neutral safety switch as soon as possible.
Q: How do I test the neutral safety switch?
A: To test the neutral safety switch, you will need a multimeter. Disconnect the wires from the switch and test for continuity between the terminals. With the shifter in the “Park” or “Neutral” position, there should be continuity between the terminals. With the shifter in any other position, there should be no continuity. If the switch fails either of these tests, it should be replaced.
