How is the Speakon connector wired for REL sub?


Recently purchased a used REL T2 sub that came without the Speakon cable. I just got the Speakon connector from Parts Express but am not sure where each wire is attached on the connector. Anybody familiar with the wiring configuration on these cables? Which pin gets left, right and ground? Thanks.

I'll try that tomorrow. Decided to hold off hooking it up until tomorrow. If I blow something up I'll be up all night thinking about it.
Thanks again for your valuable help here.
Built the cable and decided to try it out on my Harman Kardon HK6350 integrated amp instead of the Primare. The cable works fine. My thanks to BRF and Almarg for the assist.
REL subs are the best in the market. Play it Loud!

Hey guys 

just took possession of a REL S5 sub today. Got it connected to the back of my amp correctly, only issue I'm not quite feeling any thump or oomph while playing music!!! I can hear the gentle bass but definitely not feeling or enveloped by it. 

Ive got the speakon volume at 12 O clock and the crossover also at 12 O clock which would be 60 hertz. 

Sub is located in a corner behind the right main speaker positioned diagonally. 

Just wondering if I'm doing sum wrong! 

Thanks for your help
