FAQ

Modifying door harnesses involves adding the missing wires to your door harness to achieve plug-and-play functionality. This is a $52.95 kit, and is the preferred method for those with 2015.5+ trucks.

Hardwiring involves running loose wires through the door boot to the fuse box &/or BCM to get the mirrors fully functional. We provide instructions and a video, and this is the preferred method for those with 2014 and early 2015 trucks.

Swapping door harnesses involves purchasing complete new door harnesses from a dealer ($200+) to achieve plug and play functionality. This is the least common option due to the cost.

Our diesel mirrors come equipped with a genuine OEM GM ambient air temperature sensor which is prewired and placed behind the glass before we ship the mirrors to you.

Our mirrors are fully compatible with RPO code K40 (Diesel Exhaust Brake)

It's very easy to do and it takes about 30 minutes. There is a detailed install video as well as more information on the product page: https://boostautoparts.com/products/pnp

No trucks require BCM recalibrations with Boost Auto mirrors.

Check out the dynamic pictures in the product page content section for an idea of how the lights will function.

Signal Only: The lights will only flash with signal. They will not illuminate as running light.

Signal & Running Light 1.0: The lights will flash as a turn signal. At night when the running lights are activated, the lights will operate at 50% intensity for running light, 100% intensity for turn signal.

Signal & Running Light 2.0: The lights will flash as a turn signal. At night when the running lights are activated, the lights will operate at 100% intensity for running light, 100% intensity for turn signal.

Switchback: The lights will flash as an amber turn signal during the day. At night when the running lights are activated, the lights will operate at 100% intensity in WHITE for running light. When the turn signal is activated, the lights will operate at 100% intensity in AMBER in a flashing pattern until the turn signal is de-activated (at which point it will return to a solid white light).

Smoked Dotted (Amber LED) - Amber at all times

Amber Dotted (Amber LED) - Amber at all times

Smoked Strip - Amber if signal only or signal & running light, color-changing (white running light, amber signal) if switchback

Clear Strip - Amber if signal only or signal & running light, color changing (white running light, amber signal) if switchback

The only features that will be 100% plug and play are the ones that your original mirrors were equipped with. Power fold is plug and play if you originally had it. If you didn't have it please see the question below this to understand the scope of adding it. If you choose to modify your door harness or swap door harnesses everything will be plug and play after doing that if your truck is a 2015.5 or newer. If you choose to hardwire you will need to wire in any functions (cargo, signal, running light) that the truck wasn't originally equipped with following our directions. We have very thorough instructions and videos provided with purchase that make installation a breeze. Please note memory, seat recall, and curbview assist are only supported on the power fold version. Non-Powerfold mirrors are NOT supported with memory.

If your original mirrors were power folding then the feature will be plug and play. If you did not originally have power folding mirrors you can add them, but you will need to purchase a new power-folding switch (this is offered at checkout).

Unfortunately, we do not paint the mirrors for you. Our paintable mirrors come with non-textured caps in a white/neutral color so they are fairly ready for paint. The caps come off of the mirrors so that you can paint them and just snap them on with no disassembly required.

No, this is included in the price and it is installed before the mirror is shipped to you.

The date is stamped in the corner of the door sticker in the drivers side door. It is located on the door jamb, NOT the door itself. If it was built on or before 08/14 then you have an early 2015. If it was built on 09/14 or after then you have a late 2015. If you cannot locate your build date, please email the VIN to sales@boostautoparts.com and we can look it up for you.

There are additional circuits missing in your truck. If you wish to swap door harnesses or modify your door harness you also need the RZY harness. You have the option to purchase it in the options menu above. Most customers with these trucks choose to hardwire the mirrors.

Scroll through the product page content to see the difference; it's night and day! If you have tint on your truck the high output spot light will make the world of difference. Even if you don't have tint, the high output spot light is extremely convenient!

We've included a graphic below depicting the difference in brightness between Low Output Flood Lights and High Output Spotlights

Worth Every Penny

I was blown away by these tow mirrors. They are the closest thing to OEM you can get, and possibly even better. Very well made, fits perfectly, and looks fantastic. The customization options were also really nice. Install was a breeze as well. I’m glad I went with these over the cheap Chinese knock offs.

Recent purchase

I purchased these mirrors for my husband. I have not gotten to use them myself but he has and loves them. He hasn't stopped playing with them and we are now buying a pull behind camp trailer because of them. Thank you
