Not much. You get the solenoid and installation kit listed in the how too and you're one fitting and a switch away from making it work. There isn't an adaptor with that kit that will fit into the ABS dist. block. However, there is a fitting that will go over the stock line and into the solenoid.
Cut the stock line, put on the fitting and reflare it, you're done. Wire a switch, bleed the brakes and you're on your way.
