Try some lights that you can sort of sheild with a sheet or some kind of diffuser, use white background, get the camera focused in close, You tend not to frame your plugs in the shot well, they look too far away, zoom in or get closer. Use alot of light but not direct light. Have you read the threads Afterhours had about this subject recently?
My brother is a photographer, but he knows as much about cabinetry as I do about photography unfortunately
good luck
