ok, so i really dont drive my car at night, and have only put maybe 500 miles on it the past 3 years (thats pushing it!) so i just did an led guage light swap, and noticed that when my car is on, and i turn my headlights on that my guage lights go out. this is among a few other things that happen when i turn my lights on. the tach also goes all the way down, and my other indicators such as temp and oil pressure get wacky! gas guage doesnt work either, but i was leaning towards a bad sending unit on that one...maybe not now. any ideas anyone? im so bad when it comes to wiring...
