Just reading prior post regarding sway bar harness connector. I have a lot of experience with heavy truck(highway and oilpatch)chassis and engine harness that use similar connectors that ARE NOT COMPLETELY SEALED NOR COMPLETELY WATERPROOF i have had great success with using a high quality die-electric grease on contacts within connector(clean 1st with contact cleaner+shop air) and good silicone based grease on sealing(non conection area)of connector body and seal to help eliminate moisture in connector causing corrosion related failure
WARNING NEED TO KNOW YOUR CIRCUITS HERE AS NOT A GOOD IDEA TO PUT ANYTHING ON SPEED RELATED CIRCUITS(ABS.CRANK/CAM.VSS.ETC)BUT THIS IS A GREAT HELP ON DIFF LOCK,SWAY BAR MOTOR STOCK AND AUX LIGHTING ETC CIRCUITS,also keep in mind might give chrysler tech reason to deny warranty if non-chrsler approved stuff used or in wrong places
