Thank you for the follow-up comments. My soldering venture was an attempt to diagnose the problem instead of just throwing new parts at it. Given the input provided, I plan to purchase a new RCM to replace the one I soldered. I will purchase wick and flux, to properly remove the old solder and join the new solder, and test it. This I will keep in the CF for backup. Sorry I did not include an after picture, but I will after I take it out (resolder take 1) and after I resolder it again (take 2). Thank you again, looking forward to getting this car going again after the long winter months. - myxfr
