yes the pump does as you ask. Ironic that you post this cause I just came across it a min. ago and am going to attack the RCM tomorrow. Once I found the pictures of where it was located and what it looked like I knew exactly where to go. My problem is that when I had opened that box before it didnt look like any other relay switch Ive had to replace on other vehichles and it left me confused. I'll check back tomorrow. Thanks so much for responding it is really apprectiated that you actually answered my question instead of telling me to do a search on the forum to which I have already done and read so much my eyes bleed.
