Is this like the surlybill set up? pics? how did you ground it?
yeah no ground, just a simple switch that breaks the wire. I didn't want the bright blue led that came on my switch to light up, and it doesn't. I assume the ground would have supplied the led power..I'll butt in because I'm procrastinating rather do what I'm supposed to be doing. FWIW. Jaross' description sounds fairly close to what Surly did. Jaross doesn't mention a ground while Surly does.
The most basic circuit I'm thinking is the equivalent of cutting the blue/white wire, having one end in each hand, and then touching them together when you want lights and then pulling them away when you when them off. An SPST switch. Cut the blue/white wire. One end (doesn't matter which) connects to one terminal of the switch. The other end of the wire connects to the other terminal. That sounds like Jaross.
Surly is a bit more complicated and his switch has permanently on, permanently off, or controlled by the van's timer positions.(I need to learn a CAD program. The drawing is embarrassing - MS Paint). Let's see if this is what Surly actually did. The description was a bit confusing.
