Thank you for this topic. My 02 TJ was recently a victim of car theifs. They were unable to start the jeep due to the SKIM but did manage to destroy the steering column and cut the wires to the skim module and smash it off the column. I have since replaced the steering column and only lack the SKIM module and the nessary plug that comes from the harness (they cut it off and its missing) to get my jeep back on the road. My only real challange now is finding an old harrness I can get the skim module plug from to splice into my harness.
I have the FSM but this thread along with its pictures helped out alot in seeing how its installed.
