Location

Driver's footwell, on the lower LEFT edge of the dash to the left of the steering column, in the same area as the hood release handle and the driver's-side interior fuse box. The 16-pin connector is clipped into a cut-out in the bottom edge of the dash panel and faces straight down at the floor, so you find it by looking up from the footwell rather than from the seat; on coupes it sits below the moonroof/traction-control/fog switch bank. Same position on every US 7th gen Accord - sedan and coupe, 4-cylinder, V6 and Hybrid, 2003 through 2007 either side of the 2006 facelift. The retaining clips on the bracket are known to break, so if the port seems to be missing, look for it hanging loose behind the lower dash panel rather than assuming it was never fitted.
