LMC headlight upgrade problem

Anyone every buy LMC upgraded headlight harness. I just put mine in w the new H4 bulbs. The headlights worked fine without the harness, but now that the harness is in they dont work. I have power, and 2 good grounds. I have 12v power to the back of the CHEAP CHINA relays they supply and the switched power to turn the relays on but, no go. I opened the relays and can make them work by hand but WTF theses are brand new. And they are not the typical Bosch relay either.
Anyone else have the same problem. I dont even know where to find these pieces of ****.

Found my problem. Where thr stock headlight harness plugs into thr LMC harness, the spade pushed out the back of the connector and was not making contact. Missed that earlier

The relays they send with those harnesses are crap. I cut off the plug-n-play connectors they have on the harness and made my own. Picked up a couple of bosch style relays, a couple of inline fuses, and mine work great now! Something you might want to think about, would hate to be left in the dark.

Yeah, i'd like to get the common bosch style relay, and yes a fuse or circuit braker. Right now anything is better than one blown out bulb and one non-halogen
