MAC11B problem?

[Brian Devlin]

While trying to figure out my coolant sensor problem, I noticed
something strange on my ECU harness: the wires at positions 6 and 34
have been cut. The wiring diagram shows that these would go to
ground, but I can't see the other ends. Is this an undocumented
factory change or some bad re-engineering (and maybe the cause of my
problem)?

In regards to the sensor problem:  swapped the two senders, both
sender tests OK, wire has 0 ohms,  and swapped the ECU with a
presumed good unit. Smae poor starting, same code.
