I have an old push button relay I took off of my inner fender well years ago and found it digging through all my old stuff. I remember removing it as it never worked anyway due to the relay itself or crappy wiring I replaced, but is this a push button start? What is the purpose of having it under the hood? To be able to start the car while you are working on it? Sorry if it sounds like a dumb question. Is it worth putting back on?
