67 Convertible Top Switch

I really like the idea of relays in the convertible top motor, but not be an electrician, i'm confused. The first diagram shows the existing wiring out of my 66 dart. The second one shows what I think is proper placement of the relays. My question is, on WJAJR's diagram it shows the existing feed going ????
Everyday takes me closer.
Thanks

IF your going to relays, just use a fused power wire, yeah I know the original isn't fused at the Ampmeter ....but.......... (low voltage if using a relay) the relays(they get the resettable Circuit breaker inline if possible) large gauge wire) carry the heavy load so a large gauge wire going to the switch isn't needed.
If you follow WAJARS diagram (or the opt pic in your post). you'll see that it goes to a circuit breaker that does connect to the AMP lug.
