I had no problem with the gauges at 25k miles, but didn't want to take any chances, installed Jay's solution. Now at 30k miles, no problems.
If you read the subject from page 1 through 15, it shouldn't be too difficult to build your own. And a lot less expensive than new gauges.
I would be most curious, will anyone who has installed analogdesigner's solution and had a subsequent gauge failure please post. No negative results would make the current solution seem totally satisfactory.
Thanks again Jay!
