Actually I'm confused about what the OP is doing.
If you are trying to hook up the LED replacement, it only works in one direction, and it won't blow up if you reverse it
If whatever you bought??? requires an external dropping resistor, you need to post what exactly you have
(All LEDs must have series resistors, either built in or external, or enough LEDs wired in series to "make up" a 12-14V total)
If you are trying to hook a LOAD resistor to ground, you don't want to hook it to the flasher, because it's hot all the time. You need it downstream of the signal switch
I agree with "the kid." Buy a flasher that works with LEDs
Sorry, I don't use these, and don't have your destructions.
