This would be the passenger side. But agree they don't appear to make that model with reversed (opposite) terminals anymore.

Plus my driver side doesn't have dual terminals either, so it could be a prior generation. I didn't need dual terminals on that side anyway so it wasn't a concern. And only needed duals on the pass side for a clean connection to the winch relay board.
Surprised Interstate has so few options or at least it looks that way. "My guy" seemed to have just about any config one would need. This was 4 years ago tho.
Interstate, another victim of C19 I suppose.
