It's been so long I've done it (12 months), I am probably not much help..
But not *all* of the colours match...you're best off with the pin diagrams from the ECU's..
I do remember the yellow/red and I believe one was just auto only... TPS also has an extra wire for the auto ecu to decide the kick down and things, but that is not required if you're going manual.
With your relays, the red I believe you just need to find a 12v constant, or 12v IGN (I forget which), as the r33 ecu is slightly different with the relays - and those wires don't go up into the engine bay like the 32 does. The thick black/white stripey is ground *from what I remember* so can go to chasis.. but anyhow, make sure you check.
My memory is so rusty, I really need to check the wiring again.. but that would require pulling out everything at the footwell.
