Where to connect the RS485 adapter to an EasyTouch? #181

I'm eager to try this out, but I'm not super familiar with the EasyTouch circuitry -- I ordered the recommended RS485 adapter, and I have a Raspberry Pi I'm planning to hook it up to, but my question is: where do I physically hook it up to? Does someone have some photos of the hookup?

I have a compool to easytouch upgrade board so it may look a bit different, but look for a COM port - usually a 4 wire connector (Yellow = Data+, Green = Data-). The COM port is also where you connect an indoor controller or Intelliflo pump. I used the other two wires have power on them (red is 15VDC and black is Ground). I connected this buck converter to the red/blk wires to provide power to the Raspberry Pi.

It will be the same. Pretty much anywhere you see the RS485 wires as gadget-monk indicated you can attach your D+/D-.
