My speedometer and tach were returned from the manufacturer yesterday. The backlighting did not function on those two gauges, though the four small ones work just fine. I had assumed that the pigtail and connector were tested with the gauge when the set was purchased, but that was not the case. To make a long story short, when the factory tech support verified that the gauges were fine and sent them back to me, they gave me a set of new pigtails to try. That solved the problem and I now have a brightly lit dashboard! Some of the original pigtail wires were apparently crimped on the insulation which damaged the conductors. Note to self...When things don't work like they should, trust nothing and don't assume. Check everything!
I still have a problem with the variable speed windshield wiper park feature and will have to fix that before I can re-assemble the dash.
I had expected the plating shop to have shipped the interior door handles by now, and now that the updated version of the door latch is working as designed, putting the door back together should be a half-hour job when the chromed parts show up.
In the meantime, I'm researching the things I'll need to install a temporary flexible pipe from the manifold to the muffler. I don't have a trailer to take the car to the muffler shop and was hoping to get the engine running before really cold weather arrives. I know my neighbors wouldn't enjoy hearing it running through open exhausts long enough to break in the camshaft.
