EEC Power Relay:

EEC power relays are in parallel with ignition switch and provides power to the EEC module. Power relays also provide reverse battery protection and increased load handling to improve ignition switch reliability. Refer to Figs. 12 & 12a, for EEC-IV power relay type, location and model/engine applications.
