i'm sorrie to inform you, but the DX's are NOT prewired for the door locks and power windows. I ended up getting the harness off of the EX model, strip the unnecessary wires and tapped into the ignition.
Without changing out the entire harness underneath the dash, it's very time consuming and difficult to have it all plug n' play.
like others sed, get a factory manual for wire coloring.. GOOD LUCK!!!:thumbup:
