I was only looking in the v103 section, so I never saw this! I assume these cable instructions would work for v103 too.
Initially, I tried printing today and got a probing failure. Then I took off the RAMBO cover and noticed the extruder mosfet output plug could be pushed in a tad. After this, it is printing about 44 minutes without issues and still going as I type. The temp of the bed does seem to drop sharply about 20 degrees and come back to 60 degrees. It happened twice after about 5 minutes into the print, and I just saw it again at 45 minutes into the print. I wonder if these dips point to a bad bed or bad thermistor wire? Or is it no problem at all?
