SWC connection - Atoto F7 WE in 2006 honda civic EX sedan [solved]
I hope someone has experience with this. I would like to hook up the SWC for this vehicle. This video says it can be done, but no explanation. I know from the connector not used for the install that the pink with silver and the brown with silver are the SWC. They are shown as the 2 wires at the bottom left of the pic. When I measure resistance across the terminals it changes resistance with the SWC buttons. It has 10K when no button is not pushed, and I think that may be the issue.
The Atoto has Steering Wheel Key (+) and Steering Wheel Key # (+). Both put out 3.3 v when not hooked up. The Civic wires have no voltage and are not grounded, i.e. they just make a resistive loop.
I have searched both forums and watched numerous videos but cannot find a definitive answer. I do not believe a SWC controller is required. I have also reached out to Atoto, but the language barrier and only 1 email per day is not going so well. It has been a back and forth for over a week now. What I have learned is that tying the 2 civic wires to the SWC wires doesn't work bc there is no reference to ground. I have tried other combinations as well, but I keep wondering if the 10K resistance without any buttons pushed is causing the unit not to learn properly.
Does anyone have experience with this? Thanks in advance.

I have resolved this after talking to Ernie at PAC.
He said that combining pin 2 and 12 with the pink, then brown to pin 16, chassis ground may work. He was correct. Works like a charm, and no expensive adapters required.
