1966-69 Ford Mustang Tilt-Away Steering Column Wiring Diagram & Vacuum Tests
Mustang Tilt-Away steering column vacuum and electrical schematic plus vacuum motor test: apply 14 in. vacuum, 16-18 lb pull = satisfactory.
This page is from a Ford service reference covering the Tilt-Away steering column vacuum and electrical systems, with figures and diagnosis captioned for the Mustang. Fig. 8 shows both a wiring schematic and a mechanical illustration of the Tilt-Away column: the starter safety switch (column drive position), ignition switch positions (Accy. Only, Off, On Accy. & Coil, Coil Start & Proveout), steering column solenoid, relay, door jamb switch, 7.5-amp fuse, vacuum motor, vacuum release valves, locking pawl cable, cable guides, bracket, and cable adjustment point. A wiring color code legend identifies circuit 32 (red–blue stripe), 53 (black–blue stripe), 54 (green–yellow stripe), 87 (green–orange stripe), and 297 (black–green stripe). Text sections give test procedures: the Vacuum Motor Test (apply a minimum of 14 inches of vacuum; 16–18 pounds of pull on a pull scale is satisfactory), the Vacuum Release Valve Test (using a jumper wire to the spade terminal and a 12-volt source, illustrated in Fig. 9), and the Starter Safety Switch Test (test light should glow in the drive position but not in the tilt-away position). Faint bleed-through suggests the set covers '66-'69 Tilt-A-Way steering columns.

Frequently asked questions
- What wire colors are used in the Mustang Tilt-Away steering column circuit?
- The wiring color code lists: 32 red–blue stripe, 53 black–blue stripe, 54 green–yellow stripe, 87 green–orange stripe, and 297 black–green stripe.
- What fuse protects the Tilt-Away steering column circuit?
- The diagram shows a 7.5 amp fuse in the circuit near the door jamb switch and ignition switch.
- How do you test the Tilt-Away vacuum motor?
- Apply a minimum of 14 inches of vacuum to the motor with a pull scale attached; if the motor registers 16–18 pounds of pull it is satisfactory. Then check the locking pawl cable for binding or damage.
- How do you test the starter safety switch on a Tilt-Away column?
- Disconnect the wires from the safety switch inside the vacuum motor and connect a self-powered test light. The light should glow with the steering wheel in the drive position and should not glow in the tilt-away position; otherwise the switch is defective.
- How do you release the wheel if the engine won't start and there's no vacuum reserve?
- Pull downward on the locking pawl cable manually to release the wheel.
