[KKummins]

Is this a used one?

 

[1996 12 valve]

Yes it is is ot still on the other truck

I don't think it's possible for it to be on the other truck. Could be wrong though. Are all the connectors hooked up correct? And there is a quad ADR official q & a page that you could post on or look through for more help
