I finally installed my 5k hid kit on my 14' sierra and imo they look great. I removed the intake box and removed the connection that sits on top. Put everything back on.. hids work great. . When testing the lights I accidentally turned the truck on with the intake box removed and not plugged in and the truck turned off by itself. So hooked it all back up. Turned on but check engine light is on. I drove it 10 miled didn't come off. Any ideas? Similar issues? Or should I disconnect battery?
