Ok I bought and installed a new radio headunit........I got it from cruchfield and they sent me a harness with it. I installed it with no problem and the radio works great but the stock gauges do not light up and only the turbo one works.......the oil and battery don't.......any help out there???????

 

stock gauges for a 2003 evo?

 

yup

 

did you even hook the voltage gauge to the harness and the oil gauge to the drainplug socket in the oil pan? if so then just check the connections to the gauges.
