Got all 4 o2 sensors replaced. Still getting the same 12.5 or even worse on the highway. I also have a p2096 and p2098. The codes seem like a problem with 05's, which is what mine is. I used NGK/NTK.

Mine did the same after replacing them all, but I knew it was bullshit as I was getting 16.8 mpg. The codes eventually stopped occurring on their own.
Yeah, my only worry is the 12.5 mpg. Most people seem to say the cats might be bad.
Clogged catalytic converters can be diagnosed by a vacuum test or a back pressure test before you spend the money on them. Most aftermarket catalytic converters don't perform nearly as well as the OEM ones (which are very expensive), so if they're not bad, why replace them with something worse?
The main vacuum harness is 55037637AB. The speed control vacuum harness is 52109525AD. I think they are both discontinued parts, though. However, there appears to be some inventory out there.
I found the main harness. I assume I can just use some same size vacuum hose to run to the cruise?
Yes, you certainly can. Also, if the plastic tube is fine, but the rubber ends have deteriorated, there are aftermarket rubber ends available. I think most of the chain auto parts places stock them.
