I can't seem to source the torque converter lockup plug on the chassis side. Id rather not go into the trans to hard wire it. Any suggestions?

at the back corner on the drivers side, just above the section of the pan that has the cut corner, there should be a 2 wire plug sticking out of the case. That's your TCC lockup plug.
If you don't have one, that would be noteworthy. Are you seeing P0743 codes?

I have the TCC lockup on my transmission. But I have no plug on my Jeep to plug it in. Where the plug would be is just wires. So I need the plug that goes on my Jeep to plug into the TCC lockup on the transmission. Like the actual plastic wire harness that is on the chassis side.
But having a picture of that spot on the trans case would be helpful, because given the nature of that plug it being "missing" is odd. If it were completely missing you'd be hemorrhaging ATF out the hole.
On the harness side, there is a 2 pin female connector. The plug at the transmission is a pass-thru connector, but there are 2 styles of connectors at the inside of the trans. The first style is identical in every way to the outside connector. The solenoid wiring terminates at a connector inside that trans that is identical to the connector on the harness side. The other style is more of a spade/pin setup, so that flavor of solenoid just has 2 loose wires with spade type terminals.
First style. Uses the same connector inside & outside the transmission.
Second style. Top is the inside of the trans, bottom is what sticks out through the transmission case, you can see the male pins that connect to the harness side.

I need the wire connector like this one to connect to the two wires that are hanging with no connector on them .

The only ways I know to get that connector are to scavenge one off another harness or to buy the solenoid with that same connector and splice it in.
But also I'm only aware of that one style of connector on the outside. The inside is where there is a variance in connectors, so be careful which solenoid you buy if you go that route.
But before you go and buy anything, I would like to know if you have the P0743 or P0744 codes being thrown by the computer not being able to lock up the TC? And also if you have the bare leads down by the transmission, have you strobed them at the PCM connectors to make sure that's all in place? If you don't currently have codes, it would seem to me that the PCM isn't expecting to lock up the trans.....so I'm not convinced that plugging it in will change anything for you. Was this jeep previously a manual trans?
