Hella 500 Wiring help

Im in the process of wiring up the hella 500 fog lights. Man I used to be able to wire these things up with no problem ( I def was just rigging it up) At first I wanted to do this properly and correct but now it;s getting late and cold.

What is the easiest way to wire this up, im looking to do it without getting involved with the stock lights. The light has one white wire sticking out of the back. on the inside it has the silver prong with nothing on it, that is for the blue I guess (ground?)

I have an old switch and was hoping to just run the red from the battery to the switch, black on the switch to the gournd and the black wiring to the lights, i thkn for it to work this way I would have to ground the lights, right?

I dont know I give up, any help to get this thinkg wired up asap would really help.

Even if i bypass the relay switch so its on all the time through the switch I figured would be the easiest, here is the diagram (what is required and what is extra?)

Im going to get some pics of everything while I wait for some hits. thanks again....now I know why upgraded my account, becasue this site is very useful.

you want to ground out both lights then the power need to come from the relay into the lamps. the schematic on the lights should be very straighforward.

make sure you use that relay. those lights pull some power and they will burn out the switch or the wiring to it. just ground each lamp. run the 12v wires from the lamps to the relay. ground the relay, put 12v to the relay, then 12v to the switch you want to use and the other end of the switch needs to hit the relay to trigger the relay to put power to the lamps.

definetly use the relay. put it on the top of your to do list otherwise it will never get done. Looks like you went ahead and pulled a lot off to get those on there. looks like your doing it well. dunno if your just bolting it to the plastic but id reinforce the back side of the plastic with a piece of metal or something to spread the load out. might reduce some bouncing around and keep them from ripping off.

i just installed Hella 550's on my ZJ, so hopefull i can help.

first off, where are the grounds from your lights? there should be 2 wires running from the light housing, 1 power, 1 ground. run the power from both lights to the relay. run power from the battery (+) to the relay. run your supply from the relay to the switch, and the load from the switch to the parking lights, which ever side is easiest to splice them to. if you don't care about the lights working with your headlight switch, there is no need for the parking light splice. finally, ground your switch and the relay to bare metal.

make sure you have 3 grounds: lights, relay, and switch (unless you don't care about the light on the switch, then don't ground it)

after reading your post, you do need to run through the relay, those lights draw a lot of power. the little tab on the back of the light housing is for the ground, and the white wire is for power.

and those mounts look really flimsy, i would at least get some cheap angle braces from a hardware store to give them some support

im thinking about using something like this or maybe getting a flat peice to put up against the plastic. When i mounted it to the plastic it feels like over time or quicker it would rip off on the highway. Also it seems like it would bounce around and hit the grille.
