I would be doing this on my 1994 accord lx. Right now there is an aftermarket alpine 3de-7886 3 disc player in there. Do you think if i took that unit out, the new one would slide right in w/ its mounting sleeve without any problems? How do i know if there is a dash kit in there already or not? As for a wiring harness, yeah i plan to use one of those just because plugging stuff in is real easy.
