This is a harness to prevent the bothersome check engine light and DTC P0073 on GM trucks after installing aftermarket tow mirrors. This listing comes with a jumper lead and an OEM GM ambient air sensor harness. This harness is compatible with all GM trucks 2015+.
Simply slide the pins into the passenger side connector in the correct location and turn the check engine light off!
FREE INSTALLATION VIDEO!
Good, and the video was of great help. Thank you.
Great parts worked as advertised
Extremely easy to install and just what I needed after I installed after market tow mirrors to get rid of my check engine light.
Everything was just as described. Installed aftermarket mirrors and installed the host auto harness quick and easy and check engine light turned off! Would recommend
Product received promptly and in good order. Link to installation was very helpful. Would certainly recommend product and Boost Auto. Glad I found them.
