There was discussion regarding this switch (and similar ones) being subjected to crosstalk. The way I ended up wiring it eliminated even a trace of that. I wired positive of one channel to one deck, positive of the other channel to the next deck and the returns I wired to the third deck. Since I only had a three deck switch, the returns were wired to different poles on that third deck. So everything is switched. Worked well to eliminate the crosstalk.
