The audio cable from the USB plug connects directly to the ULF-SBX-H, but a different cable is needed from the one that connects to the back of the head unit, the original has 3 wires, L, R and Gnd, the ULF one has 4, L,R,Gnd and Shield.
In the meantime if anyone has questions PM me here.
I look forward to your writeup on this, I've been wanting to add this myself for some time and plan to getting around to it in the next few months. At least until I can save up for a CIC+Combox retrofit, but then I could just use the wiring I'd retrofit in.

Great work!
