I have a base model HU I'm replacing with a JVC. Bought from Crutchfield so they sent their wiring harness for the 370Z. Thing is I can't figure out which wires are the steering wheel control, they don't match any of the posts I've seen here. Also the Crutchfield harness has the ground on the outside pin, like the 12V but on the other side. The 370Z harness has no wire here, and apparently the ground is pin 15? I do have a black wire at pin 15, very small though. Looking closer some of the wires on the Crutchfield don't have a mate on the 370Z? I'm assuming everything but remote turn-on should be wired? Here are a couple pics of the 370Z harness, what is what on this thing?
