OK so the new dash install is finally DONE! Lots of hours spent making up the huge web of wires now residing behind the instrument panel, here's the final result:
The problem with the turn signal indicators was that I had wired them backwards :oops: forgot that LED's can only be wired one direction. Switched the polarity and now it's all good! It's so nice now to see what my actual engine temp is in degrees, and the new voltmeter is so accurate I can easily tell when the alternator is charging or not.
