Neutral safety switch van wiring

Seems to be some confusion and don't think this has been addressed
1.First check faqs for remounting neutral safety switch on van column.

2.If you are going to mount column closer to dash than factory you may want to move the location up 1/2 - 3/4" to clear firewall as mounting closer will move switch closer to firewall.

the Neutral safety switch on van is usally different than original pickup tilt so you will have to do some mods if you want switch to operate properly

As you see in the pic the pickup switch has an L shaped setup for backup lights and van has 2 horizontal plugs.
If you are really lucky when you got the column you saved the 2 plugs and can just rewire the ends for the backup lights.
The neutral safety switch doesn''t require a new end
heres 2 different switches

For the neutral safety switch plug from the pickup to work on new van switch you only have to break off the little black plastic tab just below the bottom prong.
I just used a screwdriver and pushed it over
Then it will plug right in
Neutral switch done !!
next backups

For the back ups plug you either have to wire on the new flat plug if you kept it .
First few I forgot!!
Soooooooo
Cut the end (L Shaped from the pickup plug) and crimp on 2 flat spade type plugs and push those on the switch prongs

I case you are wondering I don't think you can just swap plugs as the inside the column tangs are different.

here is a pic and labels for comparison of 2 plugs

then you may still have to loosen screws holding switch and adjust for neutral unless you get lucky and line it up right the first time

hope this helps with the internal wiring for the van column
