Best place to tap wires?

I am looking at installing the passive starter kill as shown in the diagrams section. (using the power antenna wire) My question is this: what is the best place to tap into each one (ignition 12v, key side starter, motor side starter)? do the key side and motor side of the starter connections need to actually be run to the starter (relay) -- isnt this somewhat obvious, even if you wire loom them? Thanks, Justin

yes, you need to wire the key side and the starter side to the relay.   usually this is done at the ignition harness, but you could also do this under the hood if you want it to be more stealth.
