I am wondering about the power wire as the current draw for the ecu is only half amp, the manual is talking about 12 ga wire minimum for ecu power and the amp plug is designed for 22 ga??? I am following the diagram for wiring but not sure of why the confusing spec for power wire.

Best,

the 12ga wire is to the engine splice point, where power for the ignition and injectors comes from. They are the main current draw. The AMP connector can accomodate 18 ga wire which is typically used for the power and ground pins.
