Sold as a set (kit covers both sides). This wiring kit allows you to hardwire in the lighting features to your truck to add towing mirrors. This kit is used when upgrading from small mirrors to towing mirrors. This gets ALL of the lighting features working properly on properly wired towing mirrors. Lighting features include running light, turn signal, and cargo light.

This is the recommended kit for 2014 1500 trucks, and all 2015 trucks built on or before August of 2014. 

This upgrade will work for OEM mirrors (RPO code DQS or DPN) and any aftermarket mirrors that properly wire all of the wires into the OEM-style connector.

2014-2015 hardwire kit

It doesn’t look like much for the money, but the installation was made very easy by making it plug and play in the door for the extra features to work. Plus you guys did all the homework finding out which wires to tap into in order to wire them up.searching the web for mirrors
