I have a PO743 code that indicates a torque converter lockup problem. This is on a 1999 Sport. Unfortunately the trans is covered in mud...and for the life of me can't find where the solenoid connection is. I found a floating round two pin connector that looks like the tq lockup wire. But don't see where I connects. Looking at pics online where the connection is, mine has a 3 wire connector plugged in. It's on the driverside by the cooler lines see pic. All the images of the tq wires are 2 wire so no idea what this one is? So where is the tq lockup connection located on the trans?

More terrible pics...I'm wonder which trans actually is as I just bought the thing. This has a large wire connector multi pin with nothing connected which suggested a computer controlled trans..and not a 32rh?
