Independent use of Fog Light Mod

[sigepbiker]

I was able to do part one in the mod and it works great no issues.
On part two, splicing the wires from pins 17 and 16 (I also tried 17 and 2 with same result) instead of high beam and fog, i get high beam and low beam and no fog. Has any had this issue, or know of someone who has when attempting this mod? I had to repair some wiring that was cut following body repairs by a previous owner just to get the right fog working, and I don't know if other wiring was tampered with previously so I may be SOL for high beams and fogs that work on the switch.

Low beams will be on when you turn on the high beams, so you should have all three lights on.

As explained by J.A., you're trying to keep the fog circuit grounded when you turn on the high beams. Pin 16 is the ground for the low and high beams. Pin 2 is the ground for the turn signals, should work in theory, but since 16 and 17 are right next to each other, it's easier with a 3M wire tap to connect the two.

I must have missed that somewhere. I couldn't get all three though, just lo/hi and fogs switched off when high beams activated. I also threw something off when using pin 2 in the turn signals. Time to back track and figure out what all is busted now haha. Thanks.

this may be a stupid question but I am unable to get a definitive observation...is this the same process for my 4th gen SR5?

Yes.

Yes.

Thanks J.A. you rock!

Noob here. Finished the Independent Fog Mod on Sunday. Then had no fogs Tuesday AM. Checked the fuse first, then inserted spare unbent relay and the fogs were back on. Found a loose connection at male quick-disconnect. Possibly the result of overzealous crimping.

Also did the 12V constant power mod. Thanks for the procedures J.A. Fantastic web page too!

I have a 2003 4Runner that didn't come with fog lights but has the wires for them. Is there a way to connect oem fog lights to come on without the fog light switch using the factory wiring? I would like them to be on when parking lights are turned on. I can order a new headlight switch for fogs but if I can get them to work without it I would rather go the route. I bought fog lights and a relay already just have to figure out how to get the lights to come on.

Part 1 = same as described at above link.
Part 2, rather than connecting pin 16 and 17 together...connect pin 10 green w red stripe [this is the wire going to the negative side coil of the fog relay] to pin 14 solid green [this is output wire of the combination switch for tail lights going to the negative side coil of the tail relay].

Let us know how it worked.

Thanks for the reply J.A. Finally was able to do this mod and I wired it just like you said and it works perfectly. Thanks again.

 

[J.A.]

Better late than never! Glad to hear it worked out okay.

What circuit slot did you happen to use for the add-a-circuit to the fog relay? 15amp fuse used in line with the add-a-circitu for the fog relay yes? Almost forgot to ask, works for 5th Gen (2015)...I just got my SR5

I had to use an add-a-circuit:

Did it!

Hi JA!

I was curious if i could purchase one of these to complete this mod? Which one would I purchase? http://www.amazon.com/s/ref=sr_nr_p...ircuit&ie=UTF8&qid=1438354123&rnid=2470954011

Thanks for the help!

I didn't use it and don't feel it is necessary. You could use it on the 25A seat heater fuse if you have that I believe. I recommend you just do it my way as detailed on my site.

JA what is this IG relay? Ignition relay?

IG Relay powers the seat heaters via the 25A seat heater fuse when the seat heater switch is activated and the ignition switch is on.

Did this mod this past week. Good stuff. Thanks for the inspiration!

I used the EFI 10A fuse to add a circuit.
For the steering column, just grounded pin 17 wire to the steering column.

this is for sure on my list of mods to do but, does anyone know if there is a mod to run your high beams independently and with your fogs?

to be more clear, I am asking if there is a mod to run the high beams independently of the low beams. Also if possible in conjunction of the fog lights. I could not find anything on this through the search.

4th gen 4 runner headlight hi/lo issue

After i installed my halo projector headlights i noticed when i turn my highbeams on the main headlights and fog lights turn lff now where as before it just came on and i had all the lights on. Can someone explain to me why this happens now if i didnt make any modifications to the electrical system? Im confused.
