HID Appearance Driving lights

[ametsman]

I am installing these on a 97 Blazer. One of the wires is supposed to connect in to the lead light power wire. Is there some way to tell which wire this is or where I can tap into it?

Thanks,

My recommendation is to get a relay switch and tap that into the parking light circuit. Then run a power wire straight from the battery to the relay switch and hook the lights up to the relay. This will automatically turn on the driving lights when the parking lights are switch on. They will also stay on no matter what beam you have the headlights set to; high or low.
