Help with Wifi Module

Just got the Wifi Module and am getting ready to install. Have a few questions before I start. I have the OpenEVSE v4.

1.   the Red (+) lead of UBEC Power module goes to the +12v header labeled RELAY 1/2, do you connect the black to the Grounding Bar or the Ground on the OpenEVSE ground where the ground cable goes. 

2.   Do you remove the R28 resistor when adding a wifi board and using the relay 1/2 as the power?


1. The Black wire can connect to any ground. Either the Ground on the board or the block is fine.

2. No need to remove R28 anymore. The UBEC uses the more powerful 12v feed.
