First - I have no affiliation to them, but I bought their product and am very happy with it. http://speedturtleengineering.com sells a flasher that connects to the OBD plug under your Ford or Dodge Ram and it will wig wag flash the turn signals on the vehicle. The vehicle has to be running for the OBD to work, but other than that you plug it in and then put the signal wire to a 12v switch or buy the one that includes the switch and you're in business. I installed in just a few minutes another unit on the same truck another guy at the firehouse and he too is impressed.
