jayman Posted February 26, 2010 Report Share Posted February 26, 2010 so... Since i am stubborn and wont get the right harness for this swap. L67 to 94 Cutlass, So far i have the motor running, gauges working, Fans Working, Basically everything working normally except.... The range selector switch is not reading what gear its in. I now have my fancy OBD2 plug under the hood and working/reading the ECU fine, But on the LSS Harness there was a plug missing for the second range selector switch, i had found it from the interior harness and from mitchel all i need from it is the Trunk release and the ground. So i have it grounded, Now Mitchel also says that from the LSS the range selector switch runs through the Dash Cluster, (which i don't have) and then to the computer. After looking at the GTP ECU diagram is shows pins that read the selector switch right from the ECU where the LSS doesn't. So i re-pinned the ECU plug to match this and wired it to the First range plug, and still no luck.. My questions are.. is there a way to bypass it past the cluster? Can the ECU be flashed to become a different ECU? or what should i do? of course instead of getting a new harness and ECU lol Worse case i guess sill have to invest in these parts, but so far this swap has only cost me time, which here in Niagara falls, this time of year all we have is time lol Also off topic. i have found that the Harness for the Coil has a loose connection and sometimes prevents the Injectors from opening. Anyone have the same problem? and is there an easy fix for this? Thanks again 'j Quote Link to comment Share on other sites More sharing options...

AL Posted March 6, 2010 Report Share Posted March 6, 2010 I really dont know what to tell you... Flashing the PCM might do it but the computer doesnt really know what to do when its repinned... Hope that makes sense Quote Link to comment Share on other sites More sharing options...
