Hi. Fixture wire is 2 black.. 1 side writing on it.
Wall has 1 gray and 1 yellow.
Before I start fiddling, gray would go to the black cord WITH writing and yellow to the black WITHOUT writing.
One side of the fixture wire should have a raised rib... the ribbed side may or may not have writing on it. The ribbed side is the identified wire and should go to the grey wire. The other goes to yellow.
There was a ribbed edge--NOT the wire with writing on it.
I'm all connected and working, thanks!
