Hmmm, guess I'll have to look into this a bit deeper.<br>
<br>
Okay, I just looked thru my stash of instrument panel bits and came up with 2 <br>
different styles of bulb holder. The early one has just a rivet holding that <br>
brass ground connector sleeve in the holder; the late one has a 1/4" tab on <br>
the outside, held on by that same rivet. That tab is marked 31 (ground.) <br>
<br>
There's no date on these parts, so I can't tell when VW started this, but <br>
probably in '69. The parts book shows the latest part for all years, so it <br>
superceeded the early bulb base.<br>
<br>
I'll have to check my cars to see if its connected, and to what.<br>
<br>
The mod I suggested might still be useful for early cars, but for later, <br>
probably '69-on, it looks like VW already took care of this, but it has <br>
connection problems.<br>
<br>
Looks like I dived down this rabbit hole too quickly.<br>
