I have two new Google Nest Thermostats that I recently installed. The upstairs thermostat doesn't need a c-wire or power connector and is working fine with no error messages. The downstairs one is working fine, but is showing the n260 error. I bought a power connector, but when I went to install it the unit has a wiring harness and not screws for the wires on the control panel. Has anyone installed a power connector through a wiring harness? If so, was it easy to do? Thanks in advance!
