Ambient air sensor harness.
The installation video was a lot of help. With the help of the video I thought the wiring harness went a lot smoother being able to reference back to the video. Great product. Thank you

This product is legit! Had the check engine light on for that dumb ambient temperature sensor and this product re installed it and now I’m back to no check engine lights! Thank you boost auto parts.
