2014-2017: DL8, DL3, Towing Mirror Upgrade – Mirrors Explained

[pgamboa]

I recently bought a 2015 2500HD with the DPN tow mirrors on it. I know this is going to sound backwards, but I actually want to put a standard size mirror on it. What all would I need to do as far as wiring to swap my DPN mirrors for a DL3 mirror? 

I’d have to see your door harness pinout. On this configuration, GM may have used a DL3 Harness since all you need to drive this mirror is the turn signal circuit. Feel free to PM me for further info.

Just wanted to send a big thank you to Phil for providing the community with his resources. I purchased a set of Syppo tow mirrors for my 2017 Sierra SLE, and Phil's DIY kit. Shipping from Phil was fast, instructions were straight forward. I started with the passenger side, took me about an hour or so from start to finish, then about 15 minutes on the driver's side. With his DIY kit, each door harness is required to be removed, then Phil's kit wired in and pinned in the door & mirror connection. I also installed the diodes for the bcm mod, that took about 30 seconds. Phil was quick to reply to a couple text messages I sent throughout the process to confirm the direction was going. I would not hesitate to work with him again in the future.

 

 

who is Phil on this thread? would like to get information on doing this upgrade. please and thank you.

Need some info about your truck. Year, trim, etc.

 

I’ve got provisions for these mirrors.

2015 gmc sierra 1500 All Terrain edition, DL3 mirrors with all of the bells and whistles...the only thing they dont do is clean themselves

[Skidsareforkids]

Do the tow mirrors all still suffer from vibrating glass? Has anyone figured a fix?

Well, with 2015 trucks, GM skimped on landing the tow mirror light circuits on early 2015 years. Then for MY (Mid Year) 2015.5, they started to.

So how to verify this?

Take a look at your door jamb connector. Remove the boot like in the pic below, and inspect the cabin side of the connector.

If you have pins 9 and 11, you’re in better shape than if you don’t.

If you do, then a set of my door harnesses with pigtail wiring for the mirror is all you would need.
