Shielded wire?
If you’re running properly shielded wire, you’ll likely be fine regardless of where you run it. Technically there’s little or no current on a p-lead in normal operation, creating little if any field. However, if you can run it away, or run it with high power or otherwise insensitive wiring, it’s lower risk. I ran one firewall penetration with powered stuff and main bus power, and another about six inches away for all the signal wiring FWF. My p-leads were shielded. Another effective practice is if signal and power must cross, route them such that they cross perpendicularly. It might cause the routing to look a little funny/sloppy, but some CAN related vehicle experience has proven it to work really well. Same rules go for audio/radio. YMMV.
