Can someone tell me what this is that I broke and if I need to hook it up for my conversion? It looks like the wires for it and the VSS come together in a single small loom and connect inside the car to a much larger loom.

Correct me if I'm wrong but if I don't connect the VSS it will only throw a code, right?

Thanks

Not familiar with that tranny but you'd think there would only be reverse lights, Neutral safety switch (And I don't even understand how that works on my T5.. So if someone cares to enlighten me.....) and VSS.

The VSS also adjusts idle and what not when decelerating with an auto I believe, as to not stall.. Or osmething like that.. :D

That should be the neutral safety switch. Good idea to have that hooked up so the car can't inadvertently be started in gear. I believe that it also functions as the reverse light switch on that application as well.

That IS the NSS/Reverse light sending unit. If it's broken, replace it.

So how does the NSS work in these modern trannies? I tried continuity on my T5 and couldn't find it doing anything? Also I can't seem to find a diagram for it to figure out HOW it works.. I just assumed the neutral safety switch was an actual switch on the clutch pedal liek I'm used to? And fox bodies have that actual switch I think?

Thanks for the info so far :thumbsup:

Now my question is did I really break it? The four pins are still there it looks like I snapped a plastic alignment tab, but the spring underneath has me concerned since I don't know its function.

It's quite broken. But it is simply a dual purpose switch. First function is neutral safety. Hooked up correctly it won't let you sart the car while it is in gear, only in Park or Neutral.
Second function is to make a connection to turn on your backup lights when you put the shifter in Reverse.
This switch affects the functionality of the transmission not at all. You can drive without it hooked up but be aware you won't have backup lights or the starting safety function.
You can simply unscrew it and screw in a replacement. It's basically a captured spring loaded ball on the other end.

Since my 1970 has the neutral/backup light switch in the shifter base, I've never had any wires connected to that switch. The 64.5 install will be another story. John
