Mono Jack Help

Hi guys, I received my 56 input kit a bit ago and I'm working on getting it wired up. I got these input jacks and just wanted to check I'm soldering them properly. This is how I think it goes.

The red line being the common wire attached to all the center pins and then to the 15 and 16 Grounds. Thanks in advance.
