I did a couple searches didn't come up with much

so I have a 2003 engine harness / engine in a 2005. From what I read it 2005 can read wideband AFR at the front sensors if switch ti wideband..
so do I have to switch an entire engine harness to a 2005?..
i have uprev and want to be able to use the wideband readings

engine is up and running on the 03 harness no problem so far with it swaped..

if I need a new engine harness what years are appropriate I would think it would be 2005 2006 2007 2008 interchangeable not sure if that's right though
Didn't revups come with a extra cam sensor?
