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

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

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.

Need location of neutral safty switch on my 1990 cadilac broughm 350 engin e


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.

I need the color of the two wires at the transmission neutral safty switch that connects the starter


You have 2 Red wires going to the starter relay, one from the positive side of the battery and the other from the starter. There is 1 wire from the starter relay to the neutral safety switch, which is Red / Lt. Blue, and 2 wires coming from the neutral safety switch, one that is Red / Lt. Blue that goes to the ignition switch, and the other which is Gray / Yellow that goes to the #30 connector in the Engine Control Module, and that is for automatic transmissions only.
