I know this has been done but, I did this today and it was a PITA. I used a wiring diagram from a 2003 Jeep FSM to identify the polarity of the wiring in both pods. The diagram showed Br/Lb wire as a negative and Br/Yl wire positive for the left pod. The right pod showed Bk/Pk wire as a negative and Db/Wt wire as positive. When I opened both sides the wires were all Br/Yl and Br/Lb. So I went off of the left pod wiring from the schematic. I have a 2004 Tj. Can anyone confirm that is right? Thanks to all who help.
