Run the power feed to the relays to your alternator power stud (fused of course)and ground wires from the lights directly to the battery negative for the least voltage drop and brightest lights. Old Jeeps frequently have corroded grounds on the grill to headlight connections. Use the original wires out of the floor switch to trigger the relays and replace the connectors on the headlights (they're available at any good parts store cheap). Hope this helps, good luck!
