Radio. im hooking a cd player up in my 94 explorer. instead of buying the harness i was an idiot and just was gonna cut and splice. well i did that and hooked my cd player up and now my 4x4 buttons, check engine light, oil lite, brake lite, or high low lite wont work. my 4x4 wont even engage. my abs lite comes on with my batt. lite when i turn the key on and that is it. my question is i have a black wire with a green stripe,a solid blue, and a light blue with a red stripe still not hooked up to my radio. is that my problem. please help
