Confused about rigging via datajack and cable Options

[pbangarth]

SR4A tells me that when using hot sim to rig a vehicle, I use commlink Response + character Intuition +1 for Initiative. But if my character has an implanted hot sim module and a datajack, and plugs directly into the vehicle to control it rather than through a commlink, what do I use instead of the commlink Response? And did I miss it in the book somewhere?

Twenty years in, I'm finally trying to understand vehicles. Pray for me.
