How-To: A10 Inside RearView Auto Dimming Mirror Conversion (DD8)

Recommended Posts

I have a 2016 Silverado 1500 LT with the DL3 side mirror upgrade using pgamboa's harness. My existing inside mirror is the non-autodim OnStar model. I'd like to get autodim plus Homelink on the mirror.. I don't need OnStar. The Gentex GENK40A4 appears to do this.. but would it work in my scenario? And would the side mirror dim?

 

There's an eBay listing right now that says it's plug-and-play "as long as your vehicle currently has the factory 10 pin auto dim mirror without OnStar." That's not what I have, but curious if pgamboa's second custom harness would get me what I'm hoping for..?

Mike,

Considering the listing states that you must have an existing dimming mirror, and without onstar, I’m not sure if you can use this mirror. It states it comes with an adapter harness as well, so no telling what they are doing with this adapter.

My $75 harness will add the dimming feature to a normal dimming mirror, which will meet their requirements... but again, I am flying blind since I don’t know what the adapter harness does.

Thanks Phil! I reached out to the seller and he replied back looking for more details about your harness, so I directed him to this thread and explained what my ultimate goal was. He did confirm that the presence of OnStar in my current setup and the lack of it on his mirror will not cause any problems. Will post an update for everyone's benefit if I hear anything.

Mike,

 

Figured I would not only get signed up on the forum (been on my to-do list for way too long!), but also figured it best to reply here so everyone can see this.  After reviewing this thread, I can say for sure that the Homelink mirrors we sell will work and will be plug & play if you do the wiring mods per Phil's info on the previous posts.  Now...keep in mind that to keep it plug & play, you'd have to be OK with the Homelink buttons only being operable when the ignition is on, as there is no constant hot wire in the existing 10 pin plug.  But if you happen to want Homelink to be operable at all times, we could separate out the Homelink power wire & you would then just need to run it to a nearby constant hot source, such as the maplights, and tap into one of those for constant power to the Homelink buttons.  We can also include in our harness the exterior dimming mirror control wires, as well as the reverse light wire too if desired.  Please note that not all of the Homelink mirrors have the exterior dimming mirror control wires, but considering we stock over 500 new and used mirrors, it won't be a problem to get you whichever mirror you'd like.  And to confirm what was mentioned in a previous post, there won't be any issues if you have an OnStar mirror and remove it...the mirror only serves the purpose of having the OnStar control buttons, so if you don't use OnStar, it won't cause any problems or error messages or anything like that.  Hope this helps!
