Hey so my clock and hazards button and a few other things were all integrated into one computer chip screen thingy. I took out that thingy to put in a large screen headunit.

I was wondering if the hazards are a single 12v + and - wire and I just gotta find out which two wires to hook a switch to or if it's more complicated than that?

What car is it? Does the indicators work with the hazard switch unplugged? If no, you’re gonna have to relocate that piece, if yes, use your probe or multimeter (probe is much faster) to find the trigger wire while turning the hazards on and off.

If the switch latches in place when you press it then it is a (-) trigger to the BCM.
- As long as the BCM sees ground from the hazard switch then the hazards will flash; remove ground and the hazards stop flashing

If you press the switch (button does not stay latched/springs back to position) and the hazards activate, then the BCM is looking for one (-) trigger from the switch to activate and one (-) trigger from the switch to de-activate
- This is similar to how the new Ford vehicle hazard switches operate
