My kit came pre-assembled (DVD was already installed in the ceneter console pocket and A/V box was on teh bracket)
I put the FM modulator right behind the passenger side kicker panel (plastic vertical panel, that you can take off after you pop the door seal on passenger side). You will see the radio connectors there, just unplug them, plug the modulator in between them. Modulator is teh black box with a small power plug and 2 connectors: one male (looks like a needle to pump the football (did I say that teh preseason is here ???!!!!

) and another is a female connector)
