I've had these seat covers for about 3 months, worked perfectly. Was finally able to get some Covercraft seat covers to match the back row, so I don't need these anymore. Was purchased from accessories.ford.com in June...
I just installed the BassPro Nano from JBL (https://www.crutchfield.com/p_109BASPRON/JBL-BassPro-Nano.html) and didn’t need to use the remote turn on wire. You just set the Auto Turn On button on the sub to ON.
