The wiring system is designed to operate with maximum performance and reliability. Adding electrical accessories to the vehicle for which it was not designed, would case abnormalities in the electrical system.

The electrical system was designed to handle one additional stop/turn light bulb per tail light circuit (one added stop/turn light bulb to the right and left side). It is not recommended to add more than one bulb per circuit as it will result in damage to the electrical system (without optional trailer Towing Wiring). It is highly recommended to order the van with the optional (UY7) trailering wire harness only, trailering provisions for towing.
