I would like to have my headlights come on with my wipers, it's on an 08 Hyundai Veracruz, any ideas wher I could find the wire colors from. I figured just adding a relay to the headlights, that's activated anytime I have the wipers on, thanks

You would have to first find your first speed wiper wire, PROBABLY* at the steering column loom, then work out if it's pos or neg going. As an example, older Hondas used a pos at rest switching neg!  This will activate a relay to bring on your headlights, again testing to find your headlioght wire.

* Some vehicles now use data or CAN** systems so you might have have to go to the wiper motor, also it probably won't work with the variable position. I wouldn't do this without access to a factory wiring diagramme.

** They use these signaling protocols for various reasons including diagnostics, it helps the dealer but doesn't help us.
