coolant temp sensor code 15

1982 Corvette was stalling, stumbling not want to run at all. Changed coolant sensor and ECM still same problem with code 15 coolant sensor.
Sounds like the ECM is not sending correct info to temp sensor but I'm not sure. Any help will be appreciated.

I have what we call a tracer schematic on my tech site at this link, if you go to it click on the lower picture, then click the + to enlarge it. Then right click on the picture, select copy image. Once you do this open your paint program and paste this into it...save on your desktop and then you can trace out the wires.
