I've got Buzzin.... Help!

Hey guys, As the title says, I've got buzzing. I just finished re-doing my motor, and everything is reinstalled back in the truck now, and i noticed when i turn my Ignition to the "ON" position, before i attempt to start it, I get a buzzing sound coming from under the driver side headlight, from this relay type connection.

(Note: I'm literally finishing everything up as we speak, odds and ends, I HAVE NOT attempted to start it yet)

Can anyone help me out here?... How to stop it? or Why its going off?...

Thanks, Madmazda.

Ok guys, Quick update, i know i just posted this, But I was just outside, and When i turn my headlights on... Buzzing stops, headlights off, and Buzzing starts again and once again this' without the truck started. just the Ignition to the "ON" position...

Madmazda, your name says it all, mad!

There is'nt anything by the headlight that could be a relay or anything of the sort that I know of...

There is a buzzer relay on your steering column that makes a buzz noise, lol!

check your coil connections

Got everything else Situated, and Truck fired up no problem first try and its running great! still Buzzing though, I dont think its associated with my Coil Todd, its specificly coming from a Relay down under my headlight driver side, on the Fender well, not Rad Support. I do believe i know what it is, I'll find out in the morning, i've done enough today! watch for an update..

More suggestions are welcome!

does your truck have daytime running lights? if so then that would be the relay for it, ive unpluged them for a few people to get rid of the DRL's, just un plug it and check your headlights high bean and all
sound like its missing a ground connection

OOHHH! DRL! OKAY! lol...

I've got a wiring diagram if you need one...

I've got no headlights at all... not even running lights, I'll try and unplug it in the morning, I do believe i think i know what the issue is. And If it is what i think it is. Which i'll check in the morning, and post it up.
