Good Method to Add Wiring For Add-Ons

Success!
I used the spade connector mentioned in post 18 to power the relay (switched 12v), the relay mentioned in post 24, and the fuse block mentioned in post 12. The unswitched 12v came from the starter relay.
I powered the fuel pump, line lock, atf temp gauge, volt gauge, oil pressure idiot light, and tach. All of the gauges and the tach are aftermarket.
Thanks for all the help.
Now to get the dash lights and dome light working…
