Recently I purchased an 04 jaguar x type with the 2.5 and it did not have a stereo in it when I bought it came with an aftermarket stereo tho so I looked up the wiring diagram and connected all the right wires and etc but still have 3 plugs that did not get used feel like I’m missing something? After I wired everything up the stereo didn’t even turn on. So wondering if anybody has a legit wiring diagram or can tell me what the issue is? Thank you
