02 tundra fog light issue

Hello all, appreciate your help!

I have an '02 tundra limited access cab with failed fog lights I need some help with. I had all 4 lights with HIDs until the L headlight died and the R fog light started to flicker. The R fog would go off on its own, and would come back on if I turned the fog light switch off and then back on. Eventually the R fog failed all together and wouldn't come back on even with flipping the switch. With only 2 opposite lights working (fog and head) I decided to just upgrade all to LEDs. The two headlights work fine now with the LEDs.

When I went to disconnect the L HID fog from the harness, I found the connection was corroded and the harness broke. I then spliced in a new harness. But now, still, neither of the fog lights work with the new LEDs. The R harness is original and doesn't work (but this was the flickering and failing HID previously). Fuse and Relay are good. Other than simply buying a cheap halogen bulb and testing to make sure both of my LEDs aren't bad, I don't know where the issue would be. I honestly don't know where to go from here. Any help is appreciated! Thanks!
