A luddite Getting the pins right


A simple question.
The pins on my Grado gold catridge are marked H, G, L, R and the connectors on my Rega are Blue Green White and Red. OK which go with which?
any help is greatly appreciated.

With few exceptions, Green and red are right channel:
Blue and Green are ground;
Red and white are hot.
HL Hot/Left should be White. I think......
