It appears these can be had all over the place, but getting the female
connector to couple withe male spade connector is a problem. To get the
actuator to work in a vanagon, one must modify the actuator harness
with the female connector. But where can the connector be found? A harness
out opf an early eurovan might work, but they are hard to find. Any
suggestions!
