I haven't done a retro in our OB but I have done a retro in my Accord from the guys at TRS. Here is a link to an install done by a customer that should answer all of your questions: Legacy quik retro install
II am more than pleased with the quality of the equipment and the tech support I received from Matt and Andrew over at TRS and you should have no problems with there stuff as long as you follow their recommendations.
