We just opened our set also, same thing. Seems Morimoto forgot to include the OEM Harnesses in all of the kits they recently sent out. We just emailed them asking what's going on. I know Morimoto switched to a new shipping platform so now they no longer hold shipments if part of the order is out of stock. They just split it automatically. So there is a chance that they shipped the lights and will ship the harnesses when they are in stock. BUT, it would have been nice if us dealers got a heads up right?
Anyway I put an email into them and i'll let you know what they say. I'll respond on here as well as your direct email since all of the Morimoto dealers are experiencing the same issue with the missing OEM LED Harness.
