BQ27Z758: Minimum number of wires I need from pack <-> host?

Tool/software:

Ideally, we want to minimize the number of wires because our connectors are large and expensive. 

I see we can communicate over 1-wire, and I see there is an ENAB + GPO pin. Does this seem correct, the lowest number of wires we would need from pack to system?

- HDQ (1 wire)

- thermistor (battery charger generally needs this for JEITA reasons)

- Pack + 

- Pack - 

Thanks! - Cameron 

I think we could ground Enable and ignore GPO
