853H hydraulics question

[mike11]

Guys I finally got the 853H delivered I bought, previous owner completely removed all electronics, which I’m ok with, I’ll add my own gauges for the engine, are there any gauges I should add to monitor the hydraulics, temp, pressure ect ?? Also if you guys can help with a pic it would be greatly appreciated. What solenoids do I need to wire to switched power to activate the aux hydraulics and hi flow aux hydraulics???

Thanks
