no, never had to replace it, but i have removed it to see if my friends crx's main relay was bad... and i have 2 ef that we can try it with though, its a 90, and a 91, which shouldnt be a problem, but i its a very easy task to do, look under your steering wheel and you will see a brown/black box that you can unplug, its about 2 inches tall and wide, ill go look outside in my parts car, ill give it you, if i can find it
