Harness
Considering I e mailed a picture of the mirror harness that I had on my mirrors the harness was not even close to what I had , used two wires in the harness , and the blue wire the test were worthless. For 120.00 dollars I could of used my own wire and saved 110.00 dollars and the cargo light works on a ground . For the money I feel I got ripped off a scam for turn signal parking lights and a cargo lamp. I should of done more research . I thought it was a basic run some wires and plug and play but it was not boost auto sent me the harness according to my application, and all it was is a hassle but I did get my mirrors hooked up and lights working but not to boost auto parts directions. Like e and learn and move on!
