SD MM style pickups Alinco or Ceramic

[Tajue17]

how can you tell the difference between the SD Musicman alinco and ceramic pickups? I want to buy another 4-string pickup like one I already have in a Stingray but I am not sure which one I have in there, I know it had orange/white/black wires? but is there a way to tell them apart by just looking at the pickup?

Belongs in the Pickup section of the forum, not the trade part. Thanks!
