Wiring up two hella 500ff to my stock bumper anyone have any diagrams how to wire it up and how do i get the dash panel off where the cigarette lighter is?
 
I don't have a diagram, but to remove the panel, just remove the screws in the face, plus two at the top, plus the one behind the ashtray (remove ashtray and look up to see it). Be gentle if that panel isn't already broken/cracked.
 
Did you also get some kind of wiring harness? You should run the lights directly off the battery. The only 12 volt wire you should tap into would be to trigger the relay in the harness, not to power up the lights.

If you have a wiring harness it should be one :banana:
 
There is no highbeam +12 volts. When you switch the HI/LO to High Beam, the Red/Yellow wire gets grounded through the HI/LO switch in the steering column if your rig is an FJ60. I think you need to back up a pace and understand how the headlights work on these rigs before you try to modify it.
 
Does your wiring diagram look anything like this, the switch can be any 12V source, but as you've read using the headlight wire is problematic.

okay ran the wires thru the fire wall hooked everything thing up yet theres still no light! what am i doing wrong :censor:

Ok Bozo! So you want to run the hella's with the High beams? with a switch? or both?

Mount a relay near the battery, Run a fused wire from the battery positive to the relay's terminal 30, now run a wire from terminal 87 to the positive lead on your Hella's. Now run the ground lead of the Hella's to the mount(with a star washer).

To turn on the lights, you'll need to trigger the relay, you'll need to run a Positive and negative to the relay terminals 85 and 86.

The head lights are always hot/live and use a negative/ground to light up the head lights.

So run 86 or 85 to a hot(you can loop it to the #30 from the battery +), now run the unused terminal(86 or 85) to the headlight trigger(or the switch in the cab)

One side of the switch to ground, the other to the relay.

The relay terminal 85 and 86 is a electric magnet, when given power they move a rod and connect terminal (close a switch)30 to 87.

Here's a pic of a relay I used for my Horns(same idea).;)
