I'm planning to start very soon on the firewall and want to know if I have everything that gets mounted on the engine side of the firewall in this list:

• 2 GPS brackets and units: One for G3X and one for 650
• Fuel Pump and cover
• Oil Tank/Bracket
• Brake Reservoir Bracket
• Overflow Bottle/Bracket
• Battery and its mounting box
• Starter Relay (diode mounted on relay)
• Master Relay (diode mounted on relay)
• 2 slow-blow fuses (?)
• Cabin Heat Splitter Box
• TCU
• Turbo Servo
• Ambient Pressure Sensor
• Grounding Bolt
• Missing anything?  Electrical components I didn't capture?

On the cabin side I have:

• Regulator
• Cabin Heat Inside Cover
• Missing anything?

I'd also like to know what must be installed before mounting the engine and what's better to wait until after the engine is mounted (if anything).

Thoughts?
