My vacuum operated locking system on one of my 420's holds vacuum but will not hold pressure. I want to check the multiport connectors and each of the acuuators individually. Where are these connectors be located? The manual does not say where they are exactly and I don't want to tear up all the interior looking for them.

Start with the 2 elements in the trunk..gas flap & trunk lock..easy,
Then lift the carpet & find the yellow vacuum/pressure line that goes to each door..
