Only way you’ll throw a code is if you you pinch, ground, short or disconnect a wire. All you’re doing is routing a wire, so moving wires around isn’t going to hurt anything. So long as you’re not routing the wire where it’ll eventually get pinched, rubbed raw, or stretched so bad that it disconnects over time, you’ll be fine. You just need to allow enough room for the plug end to pass through.
Edit: Law Abiding Biker shows the installation of that harness, I had seen it when researching how to wire heated hand grips; it requires use of that same harness. He too removed the bolts to fish the wire, so might give you an idea how to do it.
