1971 ford f100 pickup neutral safety switch wiring color code


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:
http://www.ford-trucks.com/forums/287185-back-up-light-and-neutral-safety-switch-2.html#post5601846

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

D0TZ-7B097-B .. Lever, Neutral Switch Actuator = From FTE sponsor DIRECT FORD PARTS: Ford suggested retail price: $18.72 / FTE member net: $13.23.

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.

Wires mixed on alternator


If you can give me color of wires you have. My manual is showing about 10 different combinations, depending on whether it has electric choke, idiot light or gauge, ammeter in dash etc. Main wires are Orange, or orange with light blue stripe, goes to FLD on alternator, white with black stripe goes to STA on alternator, and BAT terminal should have a black cable from battery. Be careful, there in case someone changed it to red or another colour , just be sure it's coming from battery, and it may have wire from reulator joined into it.It also shows a ground from regulator to alternator too, so just in case it's black too, don't mix those 2 up.
This may do it, but if not, get back to me.

Transmission for a 1978 Ford F100


The transmission should have the label "FMX" upon the center lower drivers side of the body. This was Ford's largest and heaviest tranny they ever made for commercial(privately owned) trucks.They only produced this model for 8 years.

1977 f 100 carging problem


run a jumper from your alternator to your battery. This is a temporary fix and should stabilize the voltage and charge the system. It seems there is a short or grounding problem somewhere between the alternator and battery, so you will need follow the wiring but given the age of the vehicle, you should change the wiring from your generator or alternator to your battery. Be sure when you are running a jumper, your gauge wire is heavy enough and make sure the wire isn't hot. This is a temporary fix so don't go on a long road trip.
