Replaced the engine relay this evening. Found out my soldering pencil was woefully under wattage. (My soldering gun has a broken tip.) Needed some wicking braid cause the solder sucker just wasn't doing it very well), Relay PN 5706 is what I removed from my RCM and that is what I put back in. Had to cut outer contact leg off as well as one frame leg as they did not match up with the board holes. With a little bending of the solder lugs I was able to "make" it fit. I'll install the RCM tomorrow and see how it goes. Been using my spare RCM and now this questionable RCM relay change will be my spare should things work out well.
