Also you need to put silacone on you distributer cap to keep the water out. also they make a jelly type stuff that you can put in the end of you spark plug wires to keep the from corroding if you get them wet and it gives them better connectivity.
Lots of silicone and plastic bags. Cover everything with openings with plastic, seal all connectors with silicone. Make sure that you also seal the plug wires and cap with silicone, they will never come off, but they will never get water in them.
I just installed my rough country 4.5in add a leaf kit on my xj and now when i turn the wheel it sounds like it is clicking or grinding. Does anyone know why or how to fix it.
