Neutral Safety Switch install problems - The 1947 - Present Chevrolet & GMC Truck Message Board Network

JointTech · 02-09-2013, 10:20 PM

Got a new NSS to replace mine as the backup lights didnt work.
Plugged the backup lights into the new unit and manually moved the tang and my backup lights came on.

woot.

Now the hard part. Installing it back on the column. The new unit is a little different than the oem.

Instructions say to move the tang so the holes line up and stick a 3/32 drill bit in it to hold it in place. Then put the truck in neutral and install the new unit.

Problems:
The tab is bigger on the new unit.

There seems to be some plastic tabs that stickup more than the OE so the unit doesnt sit flush againsnt the column.

When i hold the unit with my hand and move the gear selector I can see it push the tang to one side. But when I move it back the other way the tang doesnt move.

Just looking at it and feeling in the column there is only one finger. So I can see how it pushes the tang on the unit one way but how the heck does it push it back the other? The whole thing doesnt make sense to me. Seems like there should be a finger on both sides of the tang on the unit to push it in both directions??

So what's the trick I'm missing?

I got the part at pep boys. I looked at Brothers and their unit looks just like the OE one so Im wondering if I should just get that instead. Seems like this should work though.

hmm so Im looking at this guys picture of the OE version here http://67-72chevytrucks.com/vboard/s...d.php?t=426318

The OE one has 2 tangs that it looks like the thing in the column goes in between.

I just cleaned my old oe one up and can now see that mine HAD that as well but one side is broken off.

So that makes more sense now. So how in the heck would this other one work. the tang is a solid peice. I was thinking about cutting the white plastic at my mark there so the peice in the column would fit in.

I need to do this as well since by backup lights only work if I jiggle the column shifter. I know ac delco makes one and I'm gonna try that

the one i got was from pepboys. BWD part number S396 Switch
Doesnt seem to be the right part.

When my switch stopped working I simply bent the tabs up, took the switch apart, cleaned it up, sanded the contacts and put it back in. Took about 45 minutes and it works perfect.
