well, I've got some good news, and some bad news.

good news is, that yes both DIC's use the same plug. also good news is that there is a mating connector available from delphi that fits the plug in the dash, so theoretically a Y harness can be made. Now comes the bad news... the mating (male) connector is only available in header form (i.e. for mount on a pcb board) so while that is not ideal, it can be done with that-- either get a small piece of pcb board and mount the header on that (after drilling the appropriate ammount of holes in the board for the solder pins. or, i suppose you could solder the wires directly to the pins, without mouning on a pcb. (either way, you'd want to cover the connections with something before shoving it in the dash... like cover it with liquid electrical tape, or epoxy) i think i'd end up doing it that way.

if you want me to list out the part numbers for the connectors and pins i'd be happy to, just let me know.
