I have a couple of times. Its pretty easy. The plug that goes into the ballast only has 2 wires (as does an aftermarket one). You can either cut the factory harness and splice the 2 wires to it, or you can cut the plug off the factory ballast and splice it to the new ballast and plug it into the factory harness. The other option (cleaner and better) you can get prongs for the new ballast and plug it straight into the factory ballast and find a way to seal it from the elements. The ballasts I'm using had a 9006 plug on it, I just broke the plug and used the already there prongs and plugged them in. They fit perfectly into the stock harness. You could probably source some dead ballasts off the classifieds or maybe ebay and just use the plug from them.
