Well, I have seen the flashers with the ground wire and I assume those are for low-voltage LEDs. I just swapped out my rears for incandescent and it flashes as it should. The indicator light in the signal switch still doesn't work though but I've gone this long without it, so I guess I'll live. For the heater fans, it looks like it was a loose wire causing them to come on. I still have to grab 12v bulbs as they are illuminated switches and put the resistors inline. Since I have two fans, I'll probably look to mount the resistors to a piece of aluminum or something and hand under the dash.
