So I bought rough country 70529 led fog light conversion. It came with a relay harness. It's plug and play and you just land it on the battery and has an external push button. I would like them to work on my factory fog light switch. I know the factory fog lights are ecm controlled. So my first question is can I just hook the factory fog light wiring directly to the LED lights (2x6 led cubes) or will it be too much load? Second if that isn't an option. Can I utilize the factory fog light wiring to control the relay for the LED fogs. Thanks in advance.
