If the relay is actuated by the ME-SFI [ME] control unit (N3/10) by a ground signal at "circuit 86", it closes its power contact. When the power contact is closed the fuel pump control unit (N118) and the Fuel pump(s) (M3) are connected via "circuit 87" with voltage from "circuit 30".
The two fuel pumps are connected in parallel on model 211, 219.
