The neutral safety switch is a compulsory part of the car and any by pass operation will make you responsible for any death or injury as a result. Play safe and fix the fault causing you to consider such an ill advised decision

SOURCE: How to replace a neutral safety switch

The switch should be on the drivers side of the tranny where the shift linkage attaches to it. You will need a 13mm socket and a 15 mm socket . You will also need a heat gun , the electrical plug is glued into the connectors and must be warmed up to be removed . these rarly go bad but they do get out of adjustment / or when removing pan techs are ad to bend the shift cable bracket and get them out of adjustment . Loosen the two 13mm bolts and move it slightly in both directions and see if this fixs you problem before you change it out.

Truck won't start unless i jiggle wires under dash.


I doubt it unless you are moving the wires coming out of the switch.
Sounds like a bad connection or broken wire in the harness you are moving around.
It could involve the neutral safety switch and the harness you are moving could come from that switch.

Won't start


So it's a no crank condition? Do dash lights, gauges, and everything else work when the car won't crank over? If so, buy a cheap $5.00 testlight, and when the car won't crank, pull the small black wire off the starter solenoid. While someone holds the key in start (cranking) position and clutch pedal depressed, see if the black wire has power as it should. (Ground the testlight and just touch the wire's end terminal. If powered, the testlight will light up.) If power there, then the starter solenoid is failing. Toyota starters are very good units, but the solenoid's internal contacts get old and pitted.
If no power at the black wire, then the start circuit from ignition switch to clutch safety switch (on the clutch pedal) to starter relay to starter solenoid will have to be diagnosed. To double-check: take a single battery jumper cable and put it on the positive battery post connection. Put the other end of the jumper cable on the solenoid terminal where black wire was removed. Key can be off. Make sure car is in neutral, brake set. If starter now operates, solenoid is O.K., and it is a problem in the start circuit, -ignition switch, neutral start switch, or in the wiring.
Now find a grounding place for testlight under the dash. When car won't crank, check for power coming out of ignition switch on the black wire with white stripe. This is the start wire for the starter solenoid. Key must be in crank position. Wire shoud be powered-ignition switch is working. If no power, switch is failing. You can do the same for the clutch start switch-it's a simple switch, that when clutch is depressed switch is closed and passes power on from ignition switch to the starter relay (thus allowing power to the starter solenoid). Black wire, red stripe-this is wire from clutch switch to starter relay. When key is in crank, clutch depressed, this wire should be hot.
With me so far? Still haven't found a problem, or any loose connections? Next and last is the starter relay. It is located under dash, close to gas pedal, but under the center console, just forward and left of gear shifter. It can be tested and the wiring diagnosed there, but relays are cheap, so just swap in another and see if that helps.
If you have tried everything, and still no help, you could try a new wire from the relay to the starter solenoid. This is that black wire we started with. Older toyotas sometimes have a problem with degraded wiring not passing enough current to operate the starter

Neutral safety switch location


Normally on your transmission. You will see one or two thick wire cable looking things that connect to a black thing on the top of the transmission (sometimes it's on the side). that black box looking thing is the neutral safety switch.

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 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.

Where is the neutral safety switch location/located


On top of the transmission, right under the shift linkage. Look down under the brake master cylinder.

Neutral safety switch '97 eclipse


Under dash driver side look behind the upper arm of clutch pedal and you should see a green and black wire coming from the button (switch) assembly on the firewall. The wires go up above the clutch pedal. About in the middle of under dash on the left side you should see a white connector these wires run to. Disconnect. I just had the problem and not only starts now but not stalling like it was but it's only been one day but tested it pretty good.
