I'm making a wire harness for a motor swap I am doing to my car. I need to add a relay to the cars computer and a relay to the engine components. I've never play around with relays so here is my question. i drew up this image, will it work? or do i have everything placed in the wrong spots on the relay.
NOTE:: on the image i drew up in paint lol only shows one relay, in reality there will be two. one for the ecu and one for the engine components.
