How to replace neutral safety switch in a el ford falcon? .

Depends on what you mean by doesn't work. If you mean it doesn't go into park then no. If you mean it won't start the next time unless you jiggle the shift handle or put it in neutral, then yes, replace safety switch.

the safety switch mounts on the steering column this is it and the part # you have to take the steering wheel off with a puller mark it first so you put it back in the same position

It it won't crank in park but will crank in neutral, the problem is the neutral safety switch on the transmission.

You need to adjust the Switch, it thinks you are in Gear

Sounds like the neutral safety switch.

This could be the problem. If your dash indicator is showing reverse but the transmission is in park it could be the safety switch. I'm not talking about the safety switch in the transmission though. In automatics they put a second switch to kill the starter from engaging. You need to adjust the linkage. If your shifter isn't actually on the column but the indicators are there is a cable that attaches the floor shift to the column and that is adjustable. Put the Floor shifter in Park and turn the column section nearest the dash by hand until you find park. Then adjust the cable length as needed. If all you have is the column shift it is still a cable adjustment. Set the emergency brake, drop the shifter to low 1 and adjust the cable linkage by loosening it on the transmission and manually move it all the way to low 1 then tighten it down then move the shifter to park and repeat teh adjustment process to verify that it is properly aligned. Lock the linkage back down and see if the vehicle will start, if it doesn't move the shifter to neutral and try to start the vehicle if the vehicle starts then check the column shift safety switch at the park position to make sure it is still in place and working. Typically, if the vehicle won't start in Park or Neutral it is more likely to be the Transmission neutral safety switch.

It sounds like the shift linkage needs to be adjusted, it doesn't sound like it's all the way in park.

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.

C7TZ-7A247-A .. Neutral/Backup Switch (Motorcraft SW-600)

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.

check the neutral safety switch, sounds like it needs to be replaced. countrcurt0
