I have an 87 4000s. There are two relays under the hood by the driver side headlight. there is a single relay and a double. the single is hooked up and working fine. the double relay on the other hand was missing when i bought the car. All the wires for the headlights and turn signals are there and i bought a new double relay, but i am unsure of which wires go to which slot on the relay. I don't want to wire it wrong and do more damage. I also dont want to take it to a shop and get charged an arm and a leg. Any help would be greatly appreciated.
