Converting Manual Top to Power

[hrtbkr]

Hi
I'm converting the manual top to power in my '70 Barracuda. 
I have all the bits (switch, cylinders, lines, motor/pump).
It's already got the body wiring and I'll be able to fab the missing wiring and circuit breaker.
Does anyone have suggestions, warnings, experience doing this conversion?
I'm also looking for advice for filling and bleeding the system.
Thanks
