Did exactly the same Spectrum controller in July, taking some install hints from earlier threads. Waited till the correct harness adapter was available. Only challenge was cleaning the dash left of the steering wheel sufficiently so the no-drill adhesive solution worked. I have no regrets about my purchase of the Spectrum.I held off for a long time to see what the Mopar brake controller would be like. I feel a lot better now for giving up and buying a Curt Spectrum controller from Amazon for $135 last May. It's too bad the factory controller is such a letdown.
