2017 Momentum 388M. This is my middle Coleman Mach 15 with Heat pump. Can anyone tell me what the factory ran 2 sets of White/Orange, Black/Grey and White/Brown wires are from? I understand what the thermostat wires colors are but trying to understand what the (2) added wires on the B- are and why the compressor yellow wire is hooked up like it is and not directly to the control box. I am removing the current AC due to failure and replacing it with a unit with no heat pump. Only difference in wiring should be the Orange T stat wire not being hooked up. Replacing thermostat and control box with correct ones.
