All the switch/V/T diagrams I find show DPDT switches with 6 poles. I ordered a prewired harness, and the switch only has 4 poles. 3 on one side, and one on the other. Now I'm confused. The wiring on the switch doesn't match any of the diagrams I've found. I want N, N+B (series), B. Do I just connect the hots to the poles? That can't be right? I thought I understood basic electronics, but it seems I may be a dunce.
