Sounds like Great Idea to Me ~ If I still had an H2OBoxr in My VDubaru I'd do it to Mine
For Sure ~ Will be High on list of things to check on the next "H2OBoxr Vanagon Syndrome"
manifestation I am presented with ~ Oh But Wait > There is possibly 1 sitting in My driveway
@ this very moment ~

Fix those brittle connections! All of them. If in doubt, reflow. Not a lot of work to do, even sort of fun. Comments?

While this failure finally resulted in a shutdown many of these vehicles suffer from various gremlins that can be due to faulty electrical connections. This poor solder connection for ignition can cause all sorts of grief from poor idle, extra injector pulses, erratic tach, etc.

Imagine terminal boards using screw clamp wire terminals to a printed circuit to connect to some 40 pin flat wire ribbon connector. And then use those signals to control motion of 60 foot tall machines weighing 16 tons.
