This Video provides an explanation on how to perform a "Big 3" engine wiring upgrade. The purpose of this additional wiring it to assist with voltage drops which can be caused by using high current lights and audio equipment. This upgrade may be effective in helping with the possible dimming lights.
The upgrade tutorial was performed on a 2006 Toyota 4Runner. The wire and terminals used can be purchased at any local car audio shop or any online retailer. We used 4 gauge wiring all around in addition to factory OEM wiring.
