Thanks guys
My first attempt, I started off trying to fish Belden 1312a through 11mm four legged cable pants. In short, I gave up and started on the Belden 1311a for the surrounds and went back to the 1312a and just stripped 7 inches of the outer sleeve, installed the interconnects and called it a day.
You can see the legs on the 9mm 2 legged cable pants are quite short. I guess I should've ordered from wirecare or did I order the wrong cable pants? The four legged cable pants were fine lengthwise.
On a sidenote, you'll notice the normal heatshrink looks quite different compared to AverageJoe's cable build
