That looks great!.  Since I am taking my TV down from the front, I am mounting this inside unit there.  I found a fet black ones that will blend right in. 

On the LG upper wall unit there is only one condensate drain. There is provision on the other end for another. I hooked both ends up to minimize the possibility of leakage if the coach is not level. 


As far as the temporary set up for my front unit, I determined (after the explanation from Richard) that while my tstat is calling for hight with 12v to the correct pin, the board is not turning on the second compressor of turning the fans to high.  Not hard to work around especially since this is only temporary and I dont care about having a low setting. I’ll hjust swap the hi and low wires in the fan pins and control both additional compressor relays with the power from the compressor that does come on in the low setting.
