i just got my hands on 2 7.5 microvision lcd screens with all the wiring for a pretty good deal.(used) i have a good idea of installing it in the headrest but i'm not that clear on wiring it. i have a pioneer avic-N3 and the brain is underneath the passenger seat. from what i've heard and read about i can wire it to that but i'm not quite sure on how to do it. have any one done this before that can give me a good idea on how its done?? any tips and tricks would help.. thanks guys..
