Neutral safty switch - 1988 Honda Prelude

Back-Up Light Switch/Neutral Safety SwitchREMOVAL & INSTALLATION
(see Figure 1)

On automatic vehicles, functions of both the reverse lamps and the neutral safety switch are controlled by the shift position switch at the base of the shift selector. This multi-circuit switch also sends signals to the various electronic control units (cruise control, automatic transaxle ECU, etc.), keeping them advised of the selected gear.

To replace the shift position switch, firmly set the parking brake and block the wheels. Place the shift selector in N. Remove the console. The switch is located on the side of the shift selector, held by 2 bolts or nuts. Unplug the wiring connectors, then remove the switch.

When installing the switch, make sure the switch slider is positioned to align with the shifter arm or tab. Install the switch, tighten the retaining nuts or bolts and connect the wiring. Reinstall the console.

After installing the switch, check that the engine starts only in P or N; the starter should not engage with the shifter in any other position. Check also that the back-up lights come on when the selector is placed in R.

Hope this helps (remember comment and rated this).
