VintageAir install in TF, Any advice?
 

Started my Vintage Air install in my truck today. Only got the battery tray removed and the firewall insulation cut out for today. I welcome any advice/suggestions/cautions from anyone who has done it.

I only have the inside kit for now. I am planning on driving my truck before winter is over so I wanted the heater and controls because of that. I'll add the compressor and condenser later.
