Review on Hopkins 48505 Blade Trailer Connector by Leo Fairchild

I bought 2 of these for work scheduled next week. Revain has the best price for a quality product, especially with the add-on. I read all the customer reviews just to kill time. I'm speaking as someone who has been repairing cars for over 30 years and as a registered master technician for over 20 years. The connection diagram in the box is correct, you just have to look carefully, as intended by the manufacturer. Viewed from the back of the connector where you connect wires, not the front of the connector. If your tractor is wired incorrectly, you will need to wire or repair the trailer plug to match the tractor's electrical connector. Different car and truck manufacturers use different colored cables. Trailer manufacturers typically use standard wire colors: brown = taillights. Green = turn right. Yellow = left turn. white = earth. Blue = trailer brakes. Battery = red or black. Backup = purple or purple.
