Help: 42RLE plug identification

Need some help identifying a wiring harness for a 42rle transmission from a 2004 TJ. I'm in the middle of performing a swap between year models and transmissions... I could really use some guidance with the electrical. These are the plugs on the transmission harness I'm trying to identify. One large green plug, one large brown plug, one medium 3-wire plug, and two smaller 2-wire plugs. My thread regarding the swap can be found at:

Thanks in advance!

It will be easier to identify those connectors by the pin count & wire colors. That can be done with the FSM.

For 2004:

The range sensor has 10 pins & the power (pin 1) is violet/white & the back up feed (pin 6) is violet/black.

The crank sensor connector (black, 3 pins) has orange for the 5v supply, black/light blue for sensor ground & gray/black for sensor signal. For 2000 the 5v & signal colors are the same, the ground is brown/yellow.

Of the ones reaching to the TC, the speed sensor should be 3 wires, the TC switch 2 wires but the 231 & 241 use different ones. The 231 is the 4WD indicator but the 241 is a position sensor for the 4WD & locker signals.

The trans solenoid/pressure switch assembly is a 10 pin connector.

The torque converter clutch connector is black, has 2 wires, red/light green & orange/light green.

Thanks so much Rubi... I really appreciate it. The swap has gone pretty smoothly so far but I was starting to have my concerns with the harness conflicts. Thanks again!
