im rewiring my pfc and i dont know if im supposed to run a 12v constant to pin 1A or from a switched power source? also it says "12 volt with 7,5a fuse....is it 7 or a 5 amp fuse im running to it?

pin 1B says it need to run off ignition- thats easy

pin 2B says rpm signal- thast going to vss right? witch wire does it hook up to?



and the blue and white plugs on engine harness do i need them? im pretty sure i dont beause im running basic sensors to get my car running... thanks
