As the title suggests, none of those said lights above are working. I have checked the main fuses and relays and they all seem to be working properly, but the lights are not. Some of the said lights have been swapped over to LEDs so I’m wondering if I may have overloaded something. Where should I check?

Fog lights only come on with low-beam headlamps and ignition on in stock setup. LED headlights will also cause issues with the fog lights. My guess is its a separate problem from the other lights.

For the tail lights, could be the integration relay #2 or the taillight relay. But you're going to have to do some debugging with a voltmeter to make any progress on this one.

Schematic is here.

I checked the taillight relay and that ones fine. Where is the integration relay #2? I do have a voltmeter but I’m struggling on where to test things

To start troubleshooting, pull the tail relay and jumper pins 2 and 4 that should turn on the taillights and instrument lights.

Integration relay #2 is attached to the back of the fuse box in the driver side kick panel

I pulled the tail relay and jumped 2 and 4 and it didn’t change anything. Once I have the integration relay, what should I check?

What's a "rain light"?

What's a "rain light"?

It’s like the side markers, the lights in the blinker housing, and taillights

I took out my old integration relay and found something. Are these two black pieces supposed to be fused together? I found I have another one that doesn’t look like those pieces are fused and I’m going to place it in and see if I have any success

Got it. So rain lights are simply your word for the side marker lights. Thanks. On the two black pieces, it looks like they were simply glued together with a clear substance? This does not change anything about them - electrically connect them, etc - so it may be that the factory simply started doing this to speed assembly. So, it's not causing a malfunction that they are touching. Others with deeper circuit board knowledge may chime in...
