Weld point 21, it's just not there!

[Jinster]

I spent the afternoon installing the auto dimming rear view mirror. I need some help with finding the elusive weld point 21.

I looked under the left hand seat, unplugged the wires from the central locking unit, and unwrapped all the tape.

But I just can't find a wire that's black with blue stripe on it, much less a bunch of them. Some on the forum have said it's about an inch from the connector. It's just not there as far as I can see:

There is a blue wire with black stripe, that's not it, is it? It's not in a bunch with any crimp metal bits and it goes to the central locking unit:

I do not think MY1997 has that weld point.

The TSB says "As of MY1998".

Is there an emoticon for waving my fist in the air?

An hour of my life wasted. Dam you Porsche!!!!

Thanks Loren. :)

I am very rusty on this. But when we put in that mirror or a Traffic Pro we had to find the reverse signal wire. Is that what you are looking for. Pic is from a 2000 2.7.

Yep. Weld point 21 is supposed to be a bunch of wires held together by a "weld point" - or more like a metal crimp, I have been led to believe. Also it should be black with blue stripe. I didn't find such a wire, much less a bunch of them. I did find a blue wire with black strip, which sure looks like what you are showing in your photo. But mine is a single wire that goes to the central locking unit. I read one of your earlier posts and you guys found the whole "bunch". Mine was a just singular.

Anyway, I didn't want to splice into something I didn't know. So I ended up running a small wire all the way from the tail light to the dash under the carpet.

Now my dimming mirror works "prudently" and my reverse camera screen has an automatic trigger.
