SUMMARY
This discussion focuses on connecting FAN 2 Wiring (673 DKBLU) to the Auto pole of an AUTO/ON/OFF switch for manual fan activation. The user seeks clarification on the relay's negative connection, noting that the fan relays are grounded by the Powertrain Control Module (PCM). The proposed wiring involves connecting A10 to the AUTO side of the switch, grounding the ON side, and feeding the negative side of the coil. This wiring configuration is confirmed as correct by other participants in the discussion.
