so i have a DEH-p2900mp that i got for free, and i wanted to install it in my Scion Xa. after getting the dash out and getting the stock stereo out of the way i noticed that the connectors that feed from the car to the deck aren't the same, and im not sure what type of adapter i need to get the audio hooked up and pumpin. ive done google searches and i have been inconclusive, if anyone could point me in the right direction that would be awesome!
