;-) That's better!

That's really interesting. I saw very few Type 4s and 914s and never noticed 
that they had a 5 pin TVS where the 5th pin was left disconnected.  

I once worked on a '72 Type 3 that had been brought back from England. At least 
that was what I was told, but it was LHD. When I was checking out the FI, I 
found that the 5th pin signal wasn't getting thru, so I finally found that wire 
folded back inside the TVS connector boot. The pin was crimped on the end of 
the wire, but it appeared to have never been inserted in the connector. I 
inserted the wire and fixed a few other things and the car ran great for quite 
a few years after that.
