Hello everyone,
So I got a pair of Hella 500's to put on my truck. I followed the instructions that came with the lights but the lights wont turn on.
Before I get into details, I know my way around a vehicle and have done some electrical stuff before like install a sub or hard wire radar detector or install gauges but overall I'd say I'm still very new.
So here's the wiring diagram of how everything is wired up.
Here's whats happening. After is everything is plugged in and the power is connected, when I flip the switch, the lights dont turn on.
Here's what I know:

According to the instructions, the middle prong connects to the yellow wire on the diagram. The other two are power and ground to make the switch light up.

Here's what I know:
- Used a multimeter to ensure the red wire is indeed "hot" and bringing in power.
- Verified that the ground is working, nothing is obstructing it.
- I bought a new relay to ensure that the relay that came with the lights wasnt bad. No luck with either.
- No fuses are blown.
What I dont know:
- I dont know how to test the black wire off the relay (power for lights). I cant figure out how to set up the multi-meter to get an accurate reading. I keep getting 0's when I try.
- Dont know if the switch is bad, dont know how to test it either.
- Dont know if I need to "ground" the switch after connecting yellow wire to it even though I dont plan to have it light up yet.
