i can help u with the injector wiring, the ms is a batch fire system, so for each bank u will wire in 4 injectors i.e 4 gounds to the inj1 ground wire, and 4 hot wires form the injectors to the hot inj1 wire, same for the others side

inj1/inj2 just is just the diff banks u can out bank one or 2 on either side of the engine it does not matter.
on my car i did bank1/inj1 as the passenger side and bank2/inj2 driver side


im not sure about the relay board cause i didnt use one though
