Need to install new neutral safety switch on tranny of 1979 Ford F150 - any tips or problems I may encounter? Does the new switch need to be adjusted after install or just bolted in place? thanks, also the reverse lights do not currently work - will this switch fix that? Know any site that would give some good pics or diagrams of this install? Thanks a lot!

There is a procedure to set the switch so that it will start in neutral and park and not in drive or reverse, there are two slotted mounting holes on the switch for adjustment purposes to get it close put a scribe mark on the old switch in relation to the mounting bolt heads, when installing new switch look at the marks on the old switch to approximately locate the switch in relation to mounting bolt heads. When removing the switch make sure the truck is in park, remove the shift lever nut off the transmission where the Neutral safety switch is, then unplug the wire going to the switch, mark the bolt relation to switch as described and slide switch off the transmission shift shaft, the inside of switch hole is not round it has a flat or square type hole so it can lock into shaft and turn with shaft you may need to rotate the switch back and forth to slide it over the shift shaft when installing the new switch. bolt it on after sliding it over the shaft noting the aproximate location using the scribe marks on old switch, after assembling the shift lever and plugging the wire back in a fine adjustment of switch amy be needed if the starter doesn't activate, get under the truck loosen the hold down bolts for the switch and have an assistant hold the ignition switch to the start position while you rotate the switch when the starter activates lock down the bolts and check after to be sure the truck won't start in drive or reverse adjust accordingly.

How do you replace the neutral safety switch on a 1991 ford f150 six cylinder lariat


The neutral safety switch is located on the transmission shift lever. Its held onto the transmission case by 2 bolts in slotted holes. You will need to remove the kickdown lever. The switch will slip off the shift lever with just a little pry if dirty. Replace the switch while the transmission is in neutral. There is a small hole in the side of the switch to stick a small pin or awl into to locate the neutral position of the switch. I would try to adjust the old switch before replacing it.

Will not start, truck stuck in reverse.


If it is stuck in reverse that is a transmission problem or a break in your shift linkage. Unless you are an ace mechanic you'll need to flat bed tow it to a tranny shop for diagnosis. Because it is stuck in reverse is why it wont start, the neutral safety switch is disabling it.

Starter fuse for 1999 F150 location


There may not be a fuse in that circuit. Much more common issues involve the neutral safety switch. Try starting in neutral and then on either side of neutral. These safety switches sometimes go out of adjustment, or fail.

Bronco wont start 88 ford bronco just replaced tranny and now won't start. i've hooked everything back up but one of the wires to the transfer case bc i broke the plug in. any ideas why it wont start...


The neutral safety switch is located on the side of the transmission and it is usually attached behind the shifter linkage and it is secured with two small bolts that can be loosened up to allow for adjustment of the neutral safety switch.

To adjust the neutral safety switch place the transmission into neutral, (block the tires) there is a notch or and indent marker on the housing of the neutral safety switch that should be lined up with a line on the face of the collar that is around the shifter detent shaft, and if they are not in alignment then loosen the two bolts that secure the neutral safety switch and then turn the neutral safety switch until they are aligned and then tighten the securing bolts to the neutral safety switch, and then test the starter. If the starter fails to engage then either the neutral safety switch is faulty, the neutral safety switch has been by-passed all this time and the by-pass (I will usually find things like a paper clip shoved into the vehicles wire connector with electrical tape around it) has fallen out of the wire connector from the vehicle wiring harness, or the battery just went dead. if you have the neutral safety switch from the old transmission still available try using it to test the neutral safety circuit. I have provided you with an image to help assist you adjust the neutral safety switch.
