If you have a meter you can do a continuity test between the trans plug and the fuses at the fuse block to figure out which wire it is. If it was shifting before then that means it definitely was hooked up before, and something has happened. Have you checked all the fuses in the fuse box to make sure they are all good?
Yes all my fuses are good
