Check my wiring diagram

i had to fix all the botched wiring on my 90gsx, so i removed all add ons except my fuel pump rewire which seems to be installed correctly.

below is how i intend to reinstall my gauges. i am going to use 16g wire.

my question is what kind of relay should i get/use and where from?
what problems do you foresee?
