I would suggest a nice note written to Toyota for that answer. They were very
nice to me when I inquired as to what/where to run the DC leads on my 2009
Scion. Wrote back to me a polite three pager, suggested that I keep the HF
power and DC leads away form the computer underneath the right front seat.
Fwiw, you can unsnap the trim cover off of the inside right channel where
Toyota runs their needed stuff and hide the DC/control cable wiring inside.
On a finial note, in the past, via QST mag a few years past, did read that
early Toyota computer modules would go south in a heartbeat if very strong HF
fields were nearby.
