I'm piecing it all together slowly. I've come up with three new questions.
1) What do I hook the yellow power wire from the XM receiver to? Can I add it to the two yellow wires from the Metra harness and the Z1 harness? Have all three hooked together?
2) Wire #2 of the 07/06 bypass is from connector #2. I had set connector #2 aside as a part I won't need because I won't have an external monitor, nor a wired remote, nor a rearview camera. Although I can't figure out what the "Guide On" yellow with black stripe wire is for. Even if I don't need anything else on that connector, I'll still have to plug it in, add a wire and ground it? And to ground it, can I just screw it to something metal on the body of the car?
3) The z1 wire harness has an orange white-striped wire with an ILL tag on it. But my Metra harness' orange white-striped wire says "positive dimmer" on it. The illumination wire on the Metra harness is solid orange. Based on the labelling, I would assume the Z1's orange white-striped wire should be connected to the Metra's solid orange wire, but I thought wires were supposed to match.
Thank you again.
