? about my neutral safety switch in C10

Hey yall, got a ? about the neutral safety switch in my 76 GMC pu. When i got the truck some years ago, the wires were all mest up like under the dash, and every whare else. The truck was set up as a stick shift on the floor, but also had a steering column for an automatic, which is not original. Up till now just about every thing, such as the cab,the bed,and a wireing kit from painless has been replased. Ive got mostly every thing wired up in the engine section, the head light, and taillight sections. I am now in the dash erea, and im not sure on what to do about the neutral safety switch, since its gonna be a standered shift. The painless kit has (one) 10# guage (pur) wire, that comes out of one of the ignition switch connectors,which is cut and spade luged. Its supposed to go to the neutral saftey switch, which has 4 metal prongs on it. My ? is do i need the neutral saftey switch at all if a standered tranny is used? if so how do i wire it up. Because i dont remember if the old wires in the cab had a plug for the switch. (Please Advise)

You dont have to use the neutral safety switch but its a good idea.

Automatic and Manual transmissions are differnent. Your 4-wire setup on your automatic column is actually a neutral safety switch and backup light switch in one.

Your transmission more than likely has a NS switch built in. To use it, run the PPL wire from the ignition switch to the NS switch and then to the solenoid "s" terminal.

The neutral safety swith on your standard shift tranny should have provision for just two wires on it.

ThanX for the responces, the tranny is a saginaw 3 speed that i believe was original in the truck, and it doesnt have the provision anywhare on it for a NS switch. Now i believe the steering column, has been changed because the truck use to be a (three on the tree) but i got it with a column from an automatic truck, and a cheep shifter thru the floor. The painless kit has two light green 16 guage wires, for the back up lights. One comes from the back up lights, and hooks to the back up switch. the other one comes from the fuse panel, to the back up switch. The other 2 wires are not 10# but are (pur) 12# guage wires, one comes out of the white connector, from the ignition switch, to the starter solinoid (S Turminal). The other one come in thru the fuse panel, from the (S Turminal) on the solinoid, and it goes to the start switch. Both (Pur) 12# guage wires have the same male plug end on them, which would allow them to plug onto the NS switch on an automatic column. This is confusing me to no end because the wireing system is not one of my stong points

ns switch

Doc here,

YOU MUST ALWAYS use a Neutral safety switch!!!!!!!!!

In addition to the along that circuit you must install a clutch override....

It's JUST plain foolishness to run without them..and I believe in some states, that require inspections, is a fail, and a ticket...

Consider this..Your working on your rod, in your driveway, shut it down and leave it in first...while you go to get another Beer or drain out the last one...and your child or the kid next door crawls in Finding the keys in the ignition hits start..the car lunges forward through the house possibly killing the kid or anybody in the way...AND guess what? YOU are responsible...not the Kid.

The Neutral Safety Switch will hook up from power supplied from one side of the clutch over ride switch, the other side of the COS goes to the "Start terminal " on the ignition switch.

The Other side of the NS goes to the "S" terminal on the Solenoid at the starter...

The other two on the NS will be either up lamps .



Doc
