Question:
Im looking for a plug n play wire harness that plugs into my tekonsha Prodigy P3, 7 pin brake controller to my 2019 Subaru Ascent touring edition. And would it work with both connections, the 7 and the 4?

Hey Johnnie, we do have a plug and play brake controller install harness designed to fit your 2019 Subaru Ascent with the part # 3062-P. This plugs right into the back of your Tekonsha P3 brake controller part # 90195 and under the dash of your Ascent. The circuit that controls that brakes of the trailer that this activates will be present on the 7-way of your vehicle but it is not present on the 4-way as that's just for the basic lighting functions.
