hey guys, after taking out the added on wires under my 2000 civic ex auto, originally to fix a dash lights problem, i start the car and realize that none of my gages work. So then i try to put it in drive, and the shifter is locked in park. i went to the scrap yard and got a wire harness for the gages and radio and climate control and install that. turn car on and dashlights worked and then went out the next day. i aslo put in a ignition switch thinking it might be that and nothing!
Please help!! i checked all fuses and they all seem fine. also all break lights work.

Thanks in advance.
