The TFT is a loop and is not connected to the TCC in any way. The PCM power relay feeds power to splice #123, from there it splits into 4 circuits, one goes to the engine control - which I believe is the IDM and ICP - the second goes to terminal #71 of the PCM - third goes to terminal #97 of the PCM and the fourth goes to splice #138 which feeds all the power to the trans. it splits and feeds the EPC sol. and the second leg feeds the plastic wire harness that connect all the other solenoids in order TCC - Coast clutch - shift 2 - and shift 1. All the grounds are made at the PCM. My daughter called me today and told me her lights have never been as good as they are right now. I added an extra ground to both headlights when I changed the plugs. Good luck Lawn boy Mike OB
