Why Does the 2009 Pontiac Vibe Require a Modulite

Question:

I am getting ready to install a hitch and wires on my 2009 Pontiac Vibe not a Gt its AWD. I have found multiple ways to rig the wire system. The harness number 118460 looks the most convienient. My question is why do you have to run the cable to the battery. Most setups I have seen you just splice into the current wires. Thanks in advance.

The Vibe requires a Modulite. A Modulite is a converter that draws 12-volts of current directly from the vehicle battery which is necessary for operating the trailer lighting. The electrical system alone, without help from the battery, cannot handle the increased amperage required to run the vehicle lights as well as the lights needed for the trailer.

This is the safest option because the extra amps to power the trailer are no longer going through the expensive electrical components of the vehicle. More vehicles are using thinner gauge wire and require a Modulite, regardless of how many lights are on the trailer, simply to protect their wiring system.
