Check to see if there is any power to the black wire. Something tells me it is a ground. Also, are you sure the bulbs are good? Something to think about. A burnt out bulb causes the signal to flash really fast. On the Dakota, there are two bulbs in the front that flash. If one is bad, the other will still light (and trick you into thinking the bulb is good). However, the burned out one will cause a fast flash too. Just food for thought. I had a similar problem, both front and rear were flashing fast, and I assumed the bulbs were good. However, when I removed the front lens, one of the bulbs was bad and when replaced, everything worked.
