I just got the Hella 500 driving light kit. I got all the wiring pretty much figured out, but there are 2 things I am unsure of though. 1) What is the little blue plastic piece that came with the kit? And what does it do? It is the first picture. 2) The ground wires on the lamps came spliced (see the 2nd picture). They need to be grounded, so they need to look like the wire in the 3rd picture. Do I just need to go out and buy a ground clip or how do I go about grounding the lights themselves? Thanks.

 

Picture #1 is showing what's commonly called a 'Scotchlok' or 'IDC'. It's used to make a running tap. Basically taps a new wire off an existing wire without cutting through it.

I'm not very fond of them - I'm more of a solder & shrink wrap type of guy. But yes, they will work 'ok'.

Random instructional usage video (Running tap example = 61 seconds into video):



Picture #2 - I assume you meant to say they came 'stripped' rather than 'spliced' - but yes, you can get crimp-on ring terminals to assist in the grounding as well.

 

Great stuff. That makes sense now. I don't know too much about wiring and stuff, but if I'm not mistaken the Scotchlok is to wire the Hellas to the high-beams. Which I read a lot of other people's post where they said they didn't want to do that; they just wanted the Hellas to be controlled solely from the switch in the cab, which is what I want to do. Well thanks! Exactly what I was looking for. Oh, and you got one hell of a truck! Looks amazing!

 

Ok, so I took my time wiring everything, and making sure I put the correct wires together, but when I hooked it up nothing happened. I made sure my grounds were good (I changed them around a few times), I checked both fuses in the wires and they are good, I made sure I had the correct wires going to the correct place (multiple times), and the lights do have bulbs in them. But, still nothing. The only thing I can think that is going wrong is the green wires going from the switch to the battery. I don't want to attach it to the high beams, so I am just hooking it to the battery. Should that wire be going to the negative part of the battery? I attached a picture of what the setup is. I'm not an artist or electrician, so sorry it's not "official" or anything. Any suggestions, or help would be more than appreciated!
