BUILDING A WIRING HARNESS - DO'S and DONT'S
Written by John Swiatek
- 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.
- Do not allow the harness to touch the exhaust or motor.
- 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.
- Use petroleum jelly on the connection points if you don't have electrical grease. This will help to slow down corrosion.
- Use only automotive rated wire and sleeving to resist oil and gas.
