I just did a preliminary install for a head unit I ordered from china. Very easy and didn't have any problems. I did have a kit from crutchfield and it had step by step that showed what to do and what not to do. They recommend removing the negative before you disconnect anything. They also recommend not disconnecting the airbag light but rather removing the light from the pannel (while still connected to harness). I think another member mentioned this also a couple posts up. Even before I put everything back together I connected the battery post and did some testing (had a wire mismatch) and then put everything back together. It all works good for me. No problems. 2012 370Z Base/Sport.
