I have the pass-through wiring hooked up on my passenger side headlight connection to a capacitor then to the relays. I don’t have the error message in my monthly Onstar report. I’m also using Hylux ballasts, so I cant speak of any issues with the Morimoto ballasts/igniter setup. If you got your stuff from TRS and you’ve got some time to swing by, I’m sure they’ll help you troubleshoot it. They’re in Atlanta and they’ve got a bunch of good folks working there.
