I have a nifty wiring quandry I'm trying to solve for my friend's Dodge pickup. The short story is that large chunks of his factory wiring harness are crispified. Part of the wiring that's toast is the headlight circuit. So, he asked me to wire up a new setup. In the rain one day since he HAD to have the truck running, I wired up a circuit using what I had which was a SPDT switch, of insufficient rating. He used it like that for a long time before the switch wore out. Now he wants me to do it again, but this time, I have time and am going to do it right using relays. Trick is, I can't think of a wiring setup that doesn't involve 2 relays. Putting in 2 relays wouldn't be the end of the world, but it just seems so logical in my mind that I can do it with 1 relay. The only 1-relay circuit I've been able to come up with involves once again pulling the power for both lights through the switch which is not acceptable. So, anyone have a solution?
