Important Mechanical & Installation Notes
-
Terminal Inspection: Before sliding the factory wire harness coupling into the new regulator, inspect your vehicle's male connector pins for corrosion or heat discoloration. Clean or replace damaged connectors to prevent circuit damage.
-
Apply Dielectric Grease: Applying a thin layer of specialized automotive dielectric grease inside the plug terminals is highly recommended to isolate moisture, dust, and electrical arcing.
-
Ground Verification: Ensure the metal chassis mounting surface is clean, rust-free, and securely fastened to provide a solid ground loop pathway for the heat-sink body.
