Every connection in an electrical circuit is equally
important.  Ground connections tend to be out in the weather (or made
of steel and placed under a common windshield leak...) and have a
disproportionate rate of problems in these vans.  In all cases they
connect to steel at some point which is a failure looking for a
chance to happen.

High-current connections have to be very good or they burn up or stop
working.  The higher the current draw, the better the connections must be.

Low-current connections (like the sender connections into the ECU)
have to be good and consistent or the ECU will see false and
intermittent data about engine conditions and cause bad/erratic
engine operation.
