yeah his dome light wouldn't come on with the doors open even. we did use a wiring harness too. he text me saying that his dad was pissed about it and that i better fix it. but he broke something in my house and i didn't see him paying for it or helping fix it. he's like "what's that got to do with anything?" i'm so ****ing pissed off. anyways. i'm not paying to have his whole dash rewired. but could i have possibly shorted anything else out? i'll check all his fuses tomorrow and see. but what if none of them are blown? also, his headunit is a kdc 222 i think. my kenwood was a kdc mp225 (whatever it says in my sig since i haven't updated). anyways. i was wondering if since it's a kenwood wiring harness shouldn't it be interchangeable with kenwood headunits? and yeah we matched all the colors up but nothing came on. idk. all i kno is i'm not paying to have it fixed if i have to so every bit of advice and suggestions is appreciated.
