What do you mean by "under the dash"?
AFAIK there are four plugs that go into the dash, one 4 pin, one left keyed 13 pin, one right keyed 13pin, and one 16 pin. None of these can fit in any of the other slots in the dash. So your statement that "each plug into any of the slots" makes no sense to me
