 trying this again. At the thermostat white and red on w2. Red just splices to a black. Buy those 2 wires get spliced together at the condenser and are landed on x2. (TRANE). The white goes to wh1 at the airhandler, and the red (which becomes black, is on wh2. How do I land these on the nest 4 wiring

They were mfr 2006.

White that was on the w2 I put on w2 on the nest, the red that was on the w2 I put on the * of the nest. Seems to be working
