1993 nissan pathfinder starter kill relay

this vehicle has  2 starter wires and I am wondering how to do a starter kill relay on it

using an audiovox aps25ch, I know how to wire it up with a single wire no problem but how do you incorporate the second starter wire into it

Thank you

Mike

alright and for the orange wire from the brain which goes to the relay to trigger it, can I just use it to go to both relays, like splice off of it
