I removed original non heated power leather seats from 1999 suburban LT and only 3 wires to seat connector and replaced with heated power leather seats with 4 wire connector. The heated seats do not work and I assume the 4 wire is power to the heat. Any idea how and where I would find or run the said wire?

Thanks in advance

Whats the color of the wires?

Why wouldn't you just add heater elements to your original seats instead of changing the entire seat? Probably would have cut your cost by more than half
