67 Convertible Top Switch

So, I add a secondary power feed to the switch? There is only one feed now, red with tracer. It comes off the post, into the circuit breaker, routes back up to the switch. But if that now feeds the relays, I need a low amp secondary feed to the switch? From the accessory position on the fuse block??? Wjajr, where did you mount the relays? Under the dash? Sorry for my ignorance but I really want to get this right!

Anyone????
