Neutral Safety Switch

Print
REMOVAL & INSTALLATION

The back-up light switch is incorporated into the neutral/park safety switch. The neutral safety switch on 1988-94 models is mounted in the steering column.

Should be part of the neutral safety switch on the column.

Check on the transmission for the neutral safety switch

Don't believe it's there. You have a buick? You must have an automatic? lThe park/neutral safety switch is usually in or on the transmission, and the wiring for it is usually ran through the electrical connector for the transmission. You would probably need a shop to test it, as they would know where and which wires to check. Likely two wires which would have continuity in park or neutral, and no continuity in other gears.
If you want to test it you would need a wiring diagram for your car-good luck.

Neutral Safety Switch ? located at the bottom of the steering column. Mine is tricky, have to pull the shift lever while turning over to get it started. happened after i replaced ignition switch & Neutral Safety Switch

I am not aware of a neutral ground switch, I presume that you are speaking of the neutral safety switch. These switches are typically located at the lower end of the steering column, and sometimes at the shift lever input on the transmission, itself.

Anything along the shift linkage, from the trans to the steering column locking tube can be connected to this switch.

The neutral safety switch is located on the top and toward the base of the steering column almost to the floorboard.

To remove or install the neutral safety switch be sure to place the shifter in the neutral position, then dis-connect the wire connector at the neutral safety switch, then remove the securing screws and then remove the neutral safety switch.

Install the new neutral safety switch and do not over-tighten the securing screws, then remove the alignment pin and re-connect the wire connector to the neutral safety switch. (be sure not to remove the alignment pin until the neutral safety switch has been installed)

Check to be certain that the vehicle only starts in "Park" or "Neutral". Here is an image to help assist you, and let me know if you require any further assistance.

Ford Neutral Safety Switch; Ford Reverse Light Switch; Backup Light Switch.

The Neutral Safety Switch wires in my 1971 Ford F100 are orange with a blue stripe.
The Reverse, or Backup Light Switch wires are black with a red stripe.

There are two sets of two wires across this combined neutral safety and backup light switch, for a total of 4 wires. Photos are at the end of this post.

The switch for the 1971 Ford F100 pickup truck is the same as in many other years and models. For details, including parts numbers, see the following quote from an expert at Ford Truck Enthusiasts:

The neutral switch also controls the backup lights, and is the same 1967/77.

There is no separate backup light switch..except on 1967/68 F350's.

Neutral switch location 1967/77:

The plastic half moon shaped neutral safety switch mounts on the outside lower portion of the steering column (NOT on the transmission!).

It's activated by an inverted Y shaped lever that snaps on the shift tube

The switch is also still available from Ford, but the website is down so I can't post the list & net prices. .

1978 is the FIRST year the F100/350's have the neutral switch mounted on the transmission. __________________

The front, steering wheel side of the neutral / reverse switch after removal from the steering column. The switch's two functions are actuated when the lever in the column moves the switch lever shown here to different positions as gears are selected.


The neutral switch is installed on the steering column near the firewall, with 5/8" bolts into the steering column (visible hole) and down column from a rectangular opening in the column housing. The actuating lever for the switch is attached to the gear shift shaft inside the housing; the lever is visibly protruding from the opening in this image.

do you get a "security" light in the dash?
