When buying a trailer light converter it is important that it is powered like this one. If not it can cause damage to the vehicles lighting system. The last car I owned that had non-powered adapter needed to have some expensive electrical components replaced because of damage caused by the trailer wiring.This kit is also very complete. It includes all needed hardware and electrical connectors. Overall I highly recommend this converter. Anyone who knows how to use a multi meter or test light will be able to install it.
