Okay, I confirmed grounds at switch and the housing for each light, all is good there. My tail lights are back again, it was the fuse block not getting a good connection at the fuse itself, a little sanding on the tabs and all is well on that front. once I had power at the block (v12.32) I hooked up the 3 prong flasher unit and it blew the inline fuse (15a) I replaced it and all was the same. I then used the 2 prong flasher unit I had laying around. It was closer to right but not quite there.

2 prong - ticks without having to depress the brake pedal in hazard and when in the right turn position. also the pilot is lit consistently unless flasher is ticking in hazard or right position. only front right light is lighting up, but with the 2 prong flasher it actually flashes instead of being solid. Left turn position gives me nothing. all lights work on the dim filament.

both power sources (from the fuse block to flasher (v12.32) and at brake switch (v12.31) ), are working

pressing the brake gives no lights but the switch is functioning properly, and has power supplied.
