1. Mount fuse close to battery +, do not cross a metal frame member before fuse (wear may cause a short). Use a secondary fuse if the primary fuse will not be close to the battery. This may happen if the primary fuse is located for easy service.
2. Do not allow the harness to touch the exhaust or motor.
3. Consider using the ground connection. If the bracket is fastened to the chassis this will provide the ground connection. If the bracket does not provide a good electrical connection, then connect a separate black wire to the nearest chassis bolt.
4. Use petroleum jelly on the connection points if you don’t have electrical grease. This will help to slow down corrosion.
5. Use only automotive rated wire and sleeving to resist oil and gas.
