Had to do this for my Halo lights (were wired wrong). They were set up as 9007s, changed to 9004s. High beam light stayed on before i swapped the wiring, swapped the wiring and the lights work fine w/o high beam indicator staying on.

I dont see you have a problem with this, your doing the same thing.

 

did you cut and splice or take apart the connector?

 

cut and splice. with shrink wrap

 

No idea. He probably had some other hack-n-fab going on though.

 

my fog lights (all four of them) stay on with the high and low beams thanks to a little piece of wire and two spade connectors.

this sounds like a good upgrade. i might do this when i get those relays and all that wire that i bought the other day into my truck.

mine will be a little brighter than just swapping the bulbs though. i'll have four fog lights and the low beams when i have the low beams on. then when i pull the switch to activate the high beams i'll have four fog lights, two high beams and four off road lights ha! and to top it off, my fogs already have full power from the battery instead of a measly 10.4 volts and the headlights will too after i'm done.

 

I had an old thread on my halos not working.

Switch the black and blue wires, I didn't hack the harness. The harness on the halos can be swapped by pushing a tiny standard screwdriver (like an eyeglass repair kit or the mini ones that come in the plastic case of different mm sizes.)

Anyway, the terminals in the halo harness had a tiny clip that you could depress when looking straight at the terminals. When you depress the clip, the whole terminal could slide backward out of the harness. Do that to both the black and blue wire and insert them until the clip engages and you're done, no hacking.

The stock harness may be different, and hacking may not be avoidable, but you can buy new harnesses at the parts store should you have to hack it up. I strongly recommend using the butt connectors that are heat wrapped with adhesive and a racheting crimping tool.

Even though the butt connectors are listed as internet only, I've seen them in the store a million times. That crimping tool has a side that pinches tighter than the other so that you can position it over the wire and not smash it, while still crimping the butt end. Use a mini torch to seal the heat shrink water tight, and you'll see a little of the adhesive "goo" out of the end.

These are the only butt connectors I use any more, period.

 

as far as taking those little clips out goes, i have a tiny flat head (the size of a toothpick only flat) that works great on them.

 

What you could do OP instead of cutting your harness, is get one male and one female 9004 connector, and you could just plug it in to your factory harness. No cutting or splicing of your factory harness required.

 

What are the benefits of a 9007 bulb over the 9004? more watts?

 

More watts and more lumens, especially on low beams.
