I'm working on my harness and want to get input before I get too much cutting done. I thought I had Manual 2.4 harness I got on Ebay. However now that I'm into it, it appears to for an slush box. I have a 4-way and 7-way connector that look like they go to the park neutral switch that bolts to the 4T40E. They are nested right by the rear O2 sensor connector by the firewall.
I think I need to lose most if not all of that wire with the exception of what would be used for the VSS and back up lamp switch. I'm more familiar with the Ecotec harness so some of the connectors are foreign to me. (I will have to put those in a different thread)
