Can anyone help I just got my prerunner bumper finished and all that's left is to install and wire up the 2 hella 500 s and the 2 hella 500ff basically the same light. Anyways I want to wire them to the old fog light connections can sum one help a diagram would b nice thanks again guys

 

so you want to run them to the stock headlight switch?

have you looked over fairlainers how to on the headlight switch mod he did to run his off the switch?

 

Yes I wanted to run it to the fog light switch and I need to wire 4hellas

 

Honestly I would just run 2 new switches. I would like to be able to turn the non ff 's on at night driving like I do mine and then the ff's seperatley for off road

 

Here is the way to use the original dash switching.
In place of the normal driving lights (if you had them) wire a relay that is activated by the old light wiring.
Connect power direct from the battery through a fuse holder to the new relay to the lights. This way no heavey current goes through the dash or original wiring.
That's it.
Notes;
1. Use at least #12 wire and a relay with contact rateings more than the total draw of all the light as well as a fuse rated the next level above total circuit draw.
2. The lights will only be activated when your low beam headlites are on.
3. This setup 'could' be questionable for legality due to the intensity and focus of the lights and may require them to be covered unless off road. (Per a state's law).
4. It is by design the lights are only activated on low beams, by Ford.

 

Ok so I decided to do the 2 new switches now how would I go about that direction

 

run this set up twice
