Are intending to plug and play, or modifying the harness connections to use this Reg/Rec? Your stock stator output should have 5 wires out: 3-Yellow, 1-White, and 1-Green. If the new R/R has 7 wires, the loose WHT and GRN need to be connected to stator plug. The loose Red to battery POS and loose BLK should be the 12v sensing wire for the Regulator. Connect it to the BLK from the key switch.
