Per the parts list, the extension cable is referred to as part number "Harness".
I found the IAT, but it was literally just laying in there without a filter on it. The other filter I was questioning was the breather. I notice I still have an underseat filter and the snorkel, but all the other plastic bits had been removed. Rather than the tiny K&N filter I expected to see on the breather, it is a hose to somewhere...probably the snorkel, but I haven't dug that far.
Got the filter installed, can see why people had a problem with them breaking. Rather than making the openings larger and letting the O-clamps do their job, they made the openings about as small as you could possibly fit on the intakes.
Thanks,
