this is how I have it wired..
Alternate 1
Or cut white and brown and solder brown wire to remaining white at trans plug
Wire white wire to pin A in speed plug
Tan/blk to pin B on speed plug

Remove pin 79 white wire and move to pin 22
Remove pin 42 and move to pin 23

I drive it slowly moves and stays around 20 are so mph.. 3rd is slipping if I get on it.. but it wasn't going into 3rd anytime before I will baby it cause maybe 3rd is still a little dry...

They should be stored in history codes, not sure what kind of scan tool you are using, but some code readers dont read abs and you need to see whats going on with the abs light

Enable all trans related dtc and make all of them MIL on first error.

DTCs (P0500, P0608, P0700 to P0724, P0740 to P0757, and P1504)

Also log both VSS speeds to see if you're getting a signal. I found my ABS light didn't clear until after both VSS were working and then driving on them for a bit.
