Any help will be appreciated.
There should be 6 wires attached to the thermostat unit.
1. Red = 12 VDC + Power
2. Blue = 12 VDC -
3. Green = A/C Fan Speed High
4. Gray = A/C Fan Speed Low
5. White = Furnace
6. Yellow = A/C Compressor
Those 4 W, B, R and G in a bundle should match up to those above. Those others are for AC and perhaps the low speed fan. It's hard to say what the mfg used for colored wire. If you have AC with 2 speeds and a furnace you do need
6 wires. I would hook up those first four and see what you got, then test the last 2 to see what happens. I have to suspect that heavy white wire is for the compressor. That's about all I can help.
