Help connecting IOT power strip 12v trigger

Hello All, any help appreciated for this very dumb question. I purchased an IOT rely which is a three outlet power strip which will switch when triggered, in this case the trigged switch from my receiver via a 3.5 mm plug.

The other end of the 3.5 wire is hooked up to a small block on the strip, with two screw down terminals. All good except my 3.5 bare wire end has three wires- a positive, a negative and a clear ground wire. Which of the two wires do I use. If its red and white, what does one do with the ground wire?...Pics showing the hook up are below. Any help appreciated for this total diy newb.

Instructions say this:
Remove the green Phoenix connector by pulling gently. It slides out horizontally. Use the screw terminals to attach two wires, ie: either -GROUND and +TRIGGER, or +VCC and -!TRIGGER. Re-insert the connector. "


Thanks

You are using the wrong 3.5 plug / cable. You need one that is TS (aka “mono”), not TRS (aka “stereo”).

Generally speaking, although you can not use a mono miniplug cable in substitution for when you need stereo, you can use a stereo miniplug cable in substitution for when you need mono if you understand what the the color coding pin out is:


https://qph.fs.quoracdn.net/main-qim...28fc7b400b00-c


https://qph.fs.quoracdn.net/main-qim...02d71a47de6d-c

Generally on a stereo wire the white wire if Left ch. [tip].
The red wire is Right ch. [ring]
The ground wire is sleeve.


So as seen in my attached pictures you would use the Left ch, tip, for your mono application, what your device seems to use, the red wire is not connected, and the wire ground (the wire's outer shield) is the sleeve.
