You will not likely find a flasher that is not load sensitive in that form factor. To run the LEDs you'll need to wire in resistors to up the wattage or adapt the wiring harness to fit a generic 2-conductor electronic flasher. Resistors wipe out any wattage saved by switching to LEDs. I'd clip the original plug and leave a little pigtail in case I'd evr want to restore the stock system, then wire on a couple plug in wire ends to fit a universal electronic flasher. The new flasher will come with a diagram that shows which terminal goes to power and which to load.
