So, I bought this 98 ex that has a few upgrades, like exaust, lowered, and air intake, It has a 99 ex motor in it,(D16Y8), but it has some electrical problems, when i press the brakes the blinker lights come on, and so does the illumination lights on my sterio( the backlights on the buttons). when i am driving and i turn and turn on my blinker, and press the brakes my blinker stops blinking but al the corner lights stay on, and when i release the brake it continues blinking. when i bought it there was an aftermarket sterio in it and he put back the stock sterio, so im thinking there is something wired wrong, but im not sure, so any help would be appreciated. thanks.
