Re: BMW E30 325 wiring diagram for injectors

Pin35 should be NBV ignition on. Pin36 earths the coil of the main relay.Pin 37 receives power from the main relay,when the relay is switched by pin 36. I'm guessing feeding power to terminal 36 may have damaged ECU. I would remove this wiring 'bodge' and fit another ECU as they are available quite reasonably and no coding/immobiliser to deal with.
