Google nest 4th gen

[Mh754v]

My old wiring( honeywell) has wires on 

G, C, R, Y, W2, and O. With W2 having 2 wires on it which are not a jumper. How do I arrange this on the Google nest. Heat pump w emergency heat.

You need to figure out where that 2-wire cables go.

Post a picture of how the cables are terminated in the air handler/furnace.

I attached another drawing... this is what I found. The two seperate wires get spliced. It's a nice mess

The white,  and red( which gets spliced to black) both end up at the condenser spliced together on x2, but are seperate at the air handler wh1 and wh2

Model number of the air handler is 2/4TEC3F36A1000A

W2 wires are spliced together at the condenser and terminate on x2.... but hey are seperate at the air handler white on wh1 and black on wh2
