Installation Guide
Mount your P3 brake control in the direction of travel
and in a location where display is viewable and buttons
are easily accessible.
Wiring Brake Control
Your P3 brake control has a unique connector located
at the back of the control. This connector allows you
two options to wire your brake control.
Option 1:
Use Pigtail Wiring Harness included. This harness can
be installed by following the Generic Wiring Guide.
Option 2:
Use an OEM specific wiring harness. If your vehicle
came with a factory tow package that included a 7-way
connector, you can purchase a Tekonsha OEM wiring
harness with the P3 connector on one end and your
specific vehicle's connector on the other.
