D3 gps in my Y33?

I just hooked up my D3 in my Y33, but I haven't figured out where to hook up my speed signal wire (pink wire) to. Does anybody know where I need to wire this to hook up my navi?

you don't absolutely have to hook up this wire (i didn't on my avic z2, cause i got lazy). it's still accurate enough for my needs, but it's up to you.

Find a wiring diagram for your car, and find the speed signal wire to either your speedo or your ecu i think.

Yeah, I found it. I was just hoping someone else knew exactly where it was and what color the wire was. Thanks anyways.

BTW, it's pin/terminal # 68 on the ecu. Feel free correct me if I'm wrong.
