[V8] Coolant Gauge wackyness***Now IC board wackyness***

... well, I opened up that 5-speed instrument cluster to try to reverse
engineer the coolant gauge circuit.  For some reason the boards inside were
interconnected with accordion shaped lengths of flexprint.  I didn't think
much about it until last night.  Sure enough, the part number is 441 919 930
AX ... which means it had been rebuilt.  Looks like VDO has adopted a fix to
eliminate those internal connectors which are so prone to becoming flaky ...


While it is great to know that I'll be eliminating the flaky connections
when I swap the IC in, it does make reverse engineering the circuit board
that drives the coolant gauge impossible without unsoldering it ... which is
not something I want to do only in the interest of science.  I have another
AT cluster in the garage ... looks like I'll need to go there for the
circuit board ...
