connector above fuse box

[slow40]

I am in the process of sorting out my wiring problem in my 89 240sx. My seatbelts won't retract and my gauge cluster is not reading right on most. Speedometer doesn't work or the tach.

I have been looking at the fsm and found that I am not getting power from my #9 fuse to either system. I have my dash out and have pulled the fuse box out a little to check for any damaged wires(didn't find any).

Well, what I am wanting to know is if there is anywhere that has a diagram for the big white connector that is above the fuse box. It has a bolt holding it in just like the ecu. Any info or input is greatly appreciated.

Oh yeah, I put 12v on to the seatbelt control unit at the wire that is supposed to get power from the fusebox and the seatbelts worked perfectly. And yes I changed the fuse!
