I ordered this harness with RCA tips and it works great interfacing to the Bose system in my Silverado. It was all plug and play connecting my Kicker amp. Really happy with this purchase and I would recommend it.
Was exactly what I needed. Very well made and fit perfectly. Fast shipping. I highly recommend this product if you are looking for something to fit 2011 F150 extended cab
