How To Perform the Big 3 Upgrade
This is a very simple upgrade that you can perform yourself in under an hour.
Figure out where all the connections for the 3 wires that you’re going to upgrade are located in your vehicle. Doing this before you get started allows you to plan ahead and to do a nicer job.
Plan the paths you’re going to take with your new wires. It’s usually a good idea to follow the same paths as the old wires.
You can leave the factory wires in place and zip tie the upgraded wires directly to them. You don’t need to remove the factory wires unless there’s no room on the posts for both sets.
You’ll need a few tools such as wrenches, sockets, ratchets, zip ties, crimpers, and your new wires. You can buy a wire upgrade kit that comes with the wires, connectors, and other accessories. The specific tools you need will vary depending on your vehicle, which is why it’s a good idea to check things out ahead of time.
You’ll likely need to crimp or screw the ring terminals to at least one end of the new wires, and it doesn’t hurt to add some solder in there for good measure. This connection needs to be rock solid.
Disconnect the negative terminal on your car’s battery to avoid causing a short or damage to any of your equipment.
Now, it’s just a matter of adding your new upgraded wires in each of the 3 locations. That’s the wire that connects the ground from the car battery to the frame of the car, the wire that connects the frame to the engine block, and the wire that connects the alternator to the battery.
It’s important to remove any paint from the frame and clean it up very well to ensure that you’ve got a perfect metal-on-metal connection. Also, don’t connect this to some flimsy little piece of metal that’s sticking out somewhere, make sure you’re connecting this wire to a major section of the chassis.
As with anything that involves electronics and high output power sources, you need to make sure you have a fundamental understanding of how electricity works and how to keep yourself safe. Even seasoned professionals can slip up and make a costly error if they aren’t being careful, so if this is new to you, take your time and double check everything.
