Weld point 21, it's just not there!


Recommended Posts

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 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.
