Ah, of course -- I didn't even think of a DPST relay to handle drivers-side both door switches at once. My problem was that I got the wrong switches, which resulted in my lights being on when the doors were closed, and thus I needed the relay to be energized when the lights were in the "off" state to invert the behavior of the switches. Not that I have any idea how much a relay draws; I really should hook one up to an amp meter someday. Now I'm strongly considering getting a DPST relay so I can try that; I only replaced the door light switch on the driver side, not both switches (the other switch is for the buzzer, right? I've never heard it, since I think the PO disconnected it). Did you find a DPST automotive relay, or use something else? On the other hand, magnetic switches can be pretty cheap and it'll plug up the other light switch hole. :) Also, I found a source for more powerful magnets than the ones that come standard with the switches, but without having to buy a whole set of them like I did. I think the ones I have are here, but it's difficult to tell without buying one. They're only $0.65 each: http://www.magnet4less.com/product_info.php?products_id=98 Here's a bunch of other magnets they sell, too: http://www.magnet4less.com/index.php? cPath=10&osCsid=26959ccf53ccc4b315c9a2faac57907b -- Joe > --- In dmcnews@xxxxxxxxxxxxxxx, Joe Angell <jangell@...> wrote: > > A DPST relay would work because it is open circiut (with a form B > switch) when the door is closed, and therefore does not draw any > current.
