Excellent idea on the thermometer!
Here it is in it's natural habitat:
Fits everything from a Buick Regal to a Suburban. It's not labeled "IN/OUT" like my old receiver and the one I have on hand
Mine is also going to be a good bit farther from the evaporator as well...
I'll probably end up with a *****in' cold accumulator it'll turn my evaporator into some kind of heater...
