woops read it again and well I guess I read it wrong..... but still its for the 8500 gvw

 

if it does have an O2 sensor i want it there so it can operate it should, but with no wires around to see if a chop job was done i can't really just add an O2 sensor if i don't have somewhere to hook it up?

it has to have something to do with those **** CA rules, has to

 

I lookd on Mitchell today in class and I confirmed that only the California model had 1 upstream o2 sensor so your federal version does NOT have one

 

awesome, i KNEW if had to be that

thank you!

 

sure thing
