here is my problem...by the way I am a mechanic of 30 years exp.. friend decides he wants to put a complete ba factory turbo motor into his ba non turbo auto wagon,no problem he turns up with complete motor,pulled out his motor leaving the auto trans still in car. now the problems start.he did not supply the ecu so I said also get wiring becuase the turbo ecu has extra plug he got both.then I find that the harness on the drivers side ie from engine fuse box is wrong so he purchased new genuine rh harness fitted up this reprogramed bcm etc. started up car engine op fine. now the speedo is in op and the p selector indicator on cluster is flashing...ran scan test its says comunication fault speed sensor a or speed sensor 1 have changed cluster to xr 6 turbo sedan still has fault checked to make sure auto harness has same pins that's ok. near the left head light there is 2 main harness connectors I have noticed one of them has an extra blue wire on the turbo harness,so when plugged to lh harness that extra blue wire is not there do I have to change left body harness also? please only reply if you have done this swap or you know for sure.
