Can someone help with wiring these three boards?

I have the Inova Micro VTX-OSD video transmitter, the Seriously Pro Racing F3 Flight Controller and the Runcam Eagle camera. I can fly with my current setup but really don't understand the best setup for these three devices. I would love to get vbat in the OSD. 

Could you show me what the best wiring configuration of these would be? The whole UART and port thing has me confused. What I'd really like is if someone could tell me which pins to connect to which and what the correct ports should be in Betaflight. I've included pics of the boards. My main goal is to get basic OSD working.

Your help is GREATLY appreciated!!!

You can connect the TX/RX on the INNOVA to one of the UART on the flight controller, then you just need to set that UART up as MSP. The INNOVA is basically a MimimOSD so the set up is nearly identical.

Here is a video showing you how to setup the INNOVA as OSD in the software.

Thanks Oscar...got it working!
