i need an iom chrysler 7 interface

umm.. get a tach wire and it shouldn't grind the starter.

to program the module do exactly like you said.  take one key apart but leave the board in it.  turn 1st key on, wait till light goes out.  Turn 2nd key on (the one thats taken apart), wait till light begins to flash (about 10 seconds).  take 2nd key out, pull board on it.  reinsert key into ignition without board.  Place module next to head of key and turn on.  Wait till light come on, goes out, then comes back on solid and goes out.  Turn key off, then turn back on with module next to head to check if it starts.  if it does, then the module programed properly.
