Keystone impact 311 adding 2nd AC

[2015 impact]

We have a 2015 keystone impact 311 that has one AC unit in the bedroom I’m adding a second unit to the garage area it is ducked and prewired for the second AC does anyone know we’re the prewired thermostat wires go to I tested them back to my existing thermostat that is not them and I don’t see any other thermostat wires available. We’re did the factory take them to?

Welcome to the forum

Odds are the thermostat wires are behind the wall in the garage. How to find them? Not sure.

Not sure how they did the 2013. Might be easiest to just put an AC with the temp dials directly on the AC. Only problem with that, reaching them in the garage.

2016 keystone impact 311 adding 2nd AC to the garage area I found the factory prewired wires for the thermostat in behind the radio/ CD player so o can put a thermostat on the garage wall next to my light switches. What’s frustrating is I asked keystone dealers and the keystone factory and no one could answer this question.

Welcome to my world. On a unit that is 7 model years old, getting any information would be a daunting task. I can tell you from first hand experience that no two units are wired/plumbed the exact same way.
