Okay, the transmission did come with something for #2, so hopefully that's just sorted out.
Since my car is an r33 gt25t and was an automatic, for #1 am I able to wire the auto speedo wires to the manual r34 speedo wires? (looks like I have to buy a r34 speedo sensor?).
For the reverse and neutral wires I am tapping into this pictures green, white and black.
