I've been following this thread and the only thing I havent verified from my cruise not working is what you suggested about the VSS. My speedo is working , but i'm not sure how the test for a signal at the PCM. Would I just test the wiring for continuity from the VSS to the PCM? I would have to figure which pin gets the input. Could a code reader confirm this signal?
My truck has a 2005 LS DBW, 6spd mtm from a CTSV. I dont have access to HP tuners, but feel this might be next. Any input would be appreciated.
