Purpose of using 897-1AH-C:

Switch high current loads (up to 70A) using a small control signal
Protect switches and ECU outputs from high current flow
Reduce wiring complexity by placing the relay near the power source/device
Isolate control circuits from power circuits (safer and more reliable)
Extend component life by reducing arcing at control switches
