So, I'm trying to move from an intimidating pile of parts to something that resembles an air conditioning system.
Thankfully I had my 11 year old help me sort some things out.
The main thing was to lay everything out and see what connects to what and if we had all the connections we needed.
When it's all in a pile it does not make much sense, so "test fitting" everything was a good use of time.
This will be the hose routing for the rear unit.
And here is my high tech drawing of how the components go together.
Red: -8AN fittings / hose
Blue: -10AN fittings/ 13/32 hose
Green: -6AN
Both service ports will be at the compressor fittings.
