wires are coming from/going to...the more complex these
damned electrical systems get, the stranger connections you see...
I had a dead dash once, and after days of trying to trace the error, it
turned out to be a bad wire on a sending switch...on the transmission!
The moral of the story? Check the most likely spots first...but don't
expect to find it either "quickly" or "on purpose" because it could
literally be ANYWHERE on the car. You might also want try keeping a
written log of the wires you have checked, as o may be able to save some
time in duplicating "apparrently different" wires which are actually running
the same connections you've already tested...
DISCLAIMER: "Or I could be wrong..." ;)
