Q: How many micro-farads? what's the capacitance? Does it have a relay inside or do i need to buy one?

There is no mictofarad listing and there is no relay nor is one needed. You connect this in parallel with the run capacitor for an extra kick. This SPP5 can be installed on all Air conditioners between 4000 and 120,000 BTU. 90v-277v. I know that it is strange not having the capacitance listed. My air-conditioning unit documentation said it was compatible with SPP5 Which I thought was strange as well. Why would the air-conditioner company indicated that you might need a booster? I don’t know. Maybe it is very common. But it works fine.

Q: does this connect to compressor or motor start capacitor? How to tell which is which?

It connects to the start capacitor.

Q: Using supco's univ. 3 in 1 electronic relay for 1/3,1/4 and 1/2 hp compressors. can't find anything for 3/4 hp. would this work and how would connect?

This unit is not heavy duty enough for larger than 1/2 hp. It wont handle the amps for larger motors. I have no idea regarding solutions for larger systems. Grainger.com carries heavier duty equipt., I'd call them.
