Hi guys,
here's a simple question I'm sure. I have no brake lights on my 41 chevy. One wire is off the pressure switch but when I hook it up...zip! Also, neither wire going to the pressure switch appears to be hot. tail lights work fine. Also the dimmer switch works fine. I'm not sure, but it looks like the brake pressure switch may be tied into the dimmer switch?

Any help would be appreciated. Thanks.
