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.

Can I check the amp's negative terminals for continuity to ground with a meter? Or check for continuity between the negative terminals?
I was about to post the following response when I saw your subsequent post, which makes this no longer relevant. But I'm submitting it anyway, as an fyi:

I'd feel very confident that doing either of those things won't hurt anything, but I'm hesitant to say that with 100.00% confidence.

What you could do instead, as a temporary connection arrangement to confirm that signals are present on the amp's - output terminals, would be to connect the + inputs of the sub to the - terminals of the amp (for each channel), and one of the - inputs of the sub to the ground screw on the back of the amp. If you hear sound from the sub with those connections, it would confirm that signals are present on the amp's - output terminals.

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!
