I have two relays installed now for my front fog lights and my rear bright
backup. I am taking power off the gray wire to the foglights out of the
main light switch.

To which terminals to I run the power to the on-off-on switch? Which are
the grounds? Which will trigger the relays.

I've looked at a bunch of them on the web, and they are almost all
different. This is a six-blade switch on the back, meant to be off in the
center and to turn on one device or the other when thrown.

Thanks,

Jim
