I'm going to be doing away with the high dollar headlight switch and all the vacuum hoses associated with it that operate the headlight doors. My question is what would be the best solenoid vacuum switch to use, I want something that will be auto parts store available. I've been looking at 4X4 vacuum solenoids and EGR solenoid valve, with the 4X4 ones I'd have to run two (open & close), the EGR ones I've been looking at have three ports so maybe they would have the two functions meaning one would do it. Here's a few pics of a 4X4 valve and a EGR valve. Any ideas, suggestions?
