Big thanks to Joe, I now have brake lights -- oddly, brake lights didn't work because of a bad hazard flasher... strange. Still struggling with the right turn signal -- the rear works only if the key is off, and there is power to its switch all the time when the key is on (even if the signal isn't). I appear to have a bad bulb socket in front right though, which may help a bit... Welcoming further opinions from anyone else, as the right turn signal issues left Joe and me scratching our heads this evening!
Thanks again, Joe :cheers:
