Since you know how to solder this will be no problem, those are solder lugs on the back. Tin the wire and heat the little lugs and melt some solder in them, push
the wire in as far as it will go while keeping the cup (lug) heated. When the solder on the wire melts also take away the iron and let it cool. Use something to hold the cable so the wire doesn't move during the cooling. Make sure you verify the lug numbers. The shield goes to pin 1, positive to pin 2 and negative to pin 3. In most cases the shield will be too much so half it and twist both then cut one off clean as close to the wire cover as possible. Make sure no little strands can touch any of the contacts.
I also like to shied the back some way. The best way is to use a metal box but you can also use shielding foil after electrical tape. If you don't want to go to the trouble try it first without and see if you pick up any RFI or EMI, if not then it's not an issue. To make it neater try to find bulk snake cable. I use Mogami W2549 for all single cables.
Some studio guys also suggest to use the same brand and model cable in the wall you use for your leads so if you plan to make cables also just buy a bunch of the same stuff to outfit the entire studio. I'm not sure why but they say not to chain different model cables from one active device to the other. But it's OK to have a different cable on the output of an active device.
