Yesterday was a day to get some of the stuff I bought over the winter put in the Challenger. One was a home link controller for the garage door. It was very easy to do . The wire plug for it is in the passengers A piller. I installed the transnitter I got from Cleveland Pick-a-part in my overhead console and just run the wires over the headliner to the A piller. Then connect the wires to the 12 pin plug in the A piller and program her in. Took about a hour to do and she works great.
