SR20 VVL OBD and Intrument Wiring Help

[daxt0r]

I have a converted vehicle with a SR20VE Engine inside.

All works fine an what not, its just two minor stuff i need help with.

1) I want to manually wire up an OBD Port to monitor and diagnose the car, what is required? How do i do it exactly?

2) My tacometer never works, and my speedometer sometimes works, any way to fix this? Since this came out a P11 Primera, will i be able to stick in a instrument cluster to get everything working?

Thankx

Or at least a simpler diagram
