Where do you plug in a Tekonsha trailer brake control to a 99' Dodge van with tow package?

Answer 1

Follow the instructions with the controller and it will be fairly easy. The trailer brake wire installed at the factory will be blue and is located either under the hood at the firewall near the brake booster or inside, under the dash or under the carpet on the drivers side floor near the firewal.

Answer 2

Check with a expert either Dodge Dealership or a place like Valley Tow Right or U-Haul. Most the time I just hard wire it into the power supply and brake light switch and ingnition hot wire. The van might have a pigtail under the dash Dealer ship or owners hand book might be helpfull finding it
