I wired a set of 10 way power, heated, memory leather seats to my WJ that came with manual cloth, I didn't even have the harness prewired for the driver's seat. Anyway, use a Power Probe to test the recline motor, or just jump it. That's a pretty easy check. As far as the wiring goes, I'm not too sure. Check out wjjeeps.com as they have pretty good wiring diagrams.
And as far as lumbar support, the wires for that run along the outside of the seat. Should just be a positive and ground wire from the switch to the motor.
