    Yes it was weird, as it flagged other codes, which I was able to sort out, but with this broken cam ground wire to X2-66 (E38) was enough to prevent the ecu from giving the OK to activate/command fuel and spark, and yet no codes or reasons in VTD, which was frustrating..... so it was back to old school.... pull it all apart.....
    I will put a photo up later of the mess, and what a L77 looks like running on 2 different combined and opened up wiring harnesses... not a pretty site.. lol
    Thanks again for help

    This was my bad, as I know that these engines will run with the cam sensor unplugged, so I "assumed" this sensor wouldn't be a problem..... wrong.... it will run with 3 wires unplugged but not just 1.... and this is enough to cut fuel and spark....
    Thanks for the help guys, much appreciated
    I have it all finished and running very nice now
    Next step is to get the VF Body Control module to run the TUTD, has anyone done this yet??? and/or got the pinouts from BCM to use.
    Or is it just easier to use the VE BCM
    Did you ever get the VF BCM pinout, or working?

    I am still struggling with start relays with 6l80e, seems easiest to just run a microswitch on the shifter, but I do use the BCM, so is there a way to get nuetral safety and a reverse light electrically via the BCM? My efforts have achieved nothing

    I have a VF manual now if anyone needs bcm info, i will have the tiptronic sorted out soon enough. Im still struggling with the neutral safety
