The point was that you added no useful information about the use of the reverse input...just said that it should have been explained rather than ignored., which is a good idea. But then you too did not explain its use. And one "?" is a question. Three "???" is a tone.

Bigger than it is? You did that a few posts up, and it hasn't improved since. I've read some of your other posts and you often have useful and helpful information to add. I'm afraid that it fell flat this time.

Well Archon, you may be right. Admittedly I am a little sensitive about safety issues and I do tend to get a little worked up. I'd like to think this is part of what make me human. Sadly, I deal with tragic situations on a regular basis because people fail to be safe and/or make good choices. I accept your point that I should have included my reasoning in the original message.

As did I for 34 years, so I understand what the point was. Unfortunately, sometimes good points get lost in the delivery. I think that we're on the same page now.

ddalder, I'm sorry you're disappointed in me. But if you'd ever experienced an auto-dim being on when backing, you'd never have mentioned your warning. Frankly, a tinted rear window hurts night backing visibility FAR MORE than any auto-dim mirror, so maybe we should hang out together in Detailing and Appearance and warn people not to tint windows?

Nobody uses the mirror when backing unless they can't turn their neck. The mirror doesn't give a wide enough field of view. If you're concerned about it, you can turn the mirror off for backing, but it'* only a matter of time before you back into something.

Hi Willwren,

Just so this doesn't get too far out of hand, I appreciate what you are saying and I do respect your opinion. My delivery could have been a little better polished, but as I mentioned it one of the previous posts this really wasn't so much about the mirror but how advice is sometimes offered (not referring to you specifically).

I'm not an engineer and will be the first to admit it. Having said this, I believe things are engineered a specific way for a reason. When any of us offer advice, it'* important to realize what we know and take for granted may not transfer with the same clarity. When safety systems of any type are involved it'* important to make certain that pertinent details are clear.

Changes and modifications seem to be what much of this forum is about and I'm just as interested in this as everyone else here. My experience with adult education, working for years in the service sector and now dealing with the sick and injured have taught me that not everyone fully understands "consequences" and not everyone will always "do the right thing". So when we offer advice or suggestions I'm simply recommending a little, or sometimes a lot of education go along with it. As we communicate with those who don't fully understand a given concept, we can help them to do so by the time we're finished. Experience has also taught me that not everyone who doesn't understand will ask.

In any event, my only hope here is that we are all diligent in providing enough detail for people to reasonably weigh risk vs benefit.

With respect,
ddalder

I just picked one up today from the junkyard as well, are those light sensitive sensors on the front and back of the mirror? I'm assuming one detects bright of day and the other for glare? And what are the other two pins for? Theres a cover over them, its located next to the three pin power harness.

94..in many cases there is no addition cover over the remaining pins. Depending on what year mirror you got, the FSM may tell us. However it'* been my experience that the other pins are simply there and not used on this particular circuit board design. GM may use the circuit board for the compass mirror as well and leave out that part of the circuitry.

In addition, some cars from 92-99 may have an unused output to the driver'* side mirror.

Looks like a diagnostic port or something.

the Mirror housing is the same for the autodim, and the compass and temp....so that other connector is for the compass and the Temp.....its not used when the mirror is only the autodim
