I just got my 6.0L running it is out of a 2003 escalade. I had the computer/wiring harness reworked by Speartech. My DBW does not work. Is there anything special that needs to be done to get the computer acknowledge the DBW? It is all from the same car and everything was sent out with my computer/wiring. I haven't got in touch with speartech yet, just thought I'd try and get some info before bugging John again.
