Sun Overseas Trading (SOT) recently came out with an upgraded voltage system that uses the latest technology to stabilize the voltage in your vehicle. This high-performance voltage system can do many things to help harness the full potential of your electrical system. Not only can this voltage system help to improve torque and throttle response, but it can also brighten headlights, reduce audio noise, improve fuel efficiency, and prolong the life of your battery.
We continued our quest for power (voltage power, that is) by installing a Hyper Voltage System (HVS) in conjunction with the Hyper Ground System we installed back in our May '03 issue. Our previous ground system used gold wires, but we decided to match all the wires and clean up the engine bay a bit by swapping in the silver ground set to match the silver wires of our new HVS. As with the ground system, the leads are made of high-quality, thick-gauge, 99.99 percent-pure copper wiring, with multilayered shielding.
The HVS offers a built-in safety feature that is designed to protect the vehicle, even if the terminals are connected to opposite lead wires. To make sure that doesn't happen, here are some detailed instructions on safety and installation. Follow along and you'll see how easy it is to increase your truck's voltage capabilities.
We started by swapping out our gold Hyper Ground wires for the silver ones. We first replaced all the grounds to the frame.
Next, we routed one of the new silver ground leads over the firewall for cleanliness, then bolted it to the firewall for a good, solid body ground. | 
Here's our engine bay, cleaned up and grounded with matching silver Hyper Ground System wiring. |
This is the Hyper Voltage System in all its glory. | 
Our battery is sitting innocently, unaware that we are about to help it with a little backup. |
Always disconnect the negative battery terminal before you begin working on your truck. | 
Find a place out of the way of any moving parts or extreme heat to put the HVS unit. It also needs to be placed close enough to the battery for the provided leads to reach. |
Once you have decided where your unit will be placed, you can disassemble the negative battery terminal to make room for the new lead. | 
Place the HVS negative (black) lead onto the negative battery terminal and reassemble the terminal. |
Now you can move to the positive battery terminal. | 
Remove the bolt holding the positive terminal in place. |
Disassemble the positive battery terminal and position the positive (red) lead from the HVS unit in place. | 
Put together the positive terminal and tighten the clamp components. |
Reconnect the positive battery terminal first and tighten all connections. | 
You can now reconnect the negative terminal to the battery. |
We didn't permanently affix the HVS box earlier because we wanted to make sure we had enough slack. You can now clean the unit and the area where you are placing the unit with rubbing alcohol. Then attach the provided pad of double-stick tape to the unit. | 
Once the unit is permanently mounted, clean up the wiring with zip ties. |
We tested the voltage before and after. We noticed that even with all of the accessories on, such as A/C, headlights, and radio, the voltage did not fluctuate as much as before, and we had a higher voltage reading with the vehicle off. | |
