How to add Foglights using OEM Wiring on the RAV4.3

OK, this is still a work in progress. i would like input / feedback from the community to help refine the documentation TIA!

And of course - be forewarned: i do not work for Toyota, am not a mechanic by profession, and should not be considered an authority on any of the systems dealt with in this write-up - so if you do this, it's at your own risk!

Much of the info and diagrams came from this document: http://techdoc.toyota-europe.com/aim...00%20539-1.pdf

Project: Add Fog Lights to RAV4.3 using OEM Wiring (USA)
  • Advantages: Simple installation, OEM quality setup, factory behavior - fogs only operate if low-beams are on, plus dash indicator light functions as designed:
  • Potential Disadvantages: factory behavior - if you want the fogs on w/o the low-beams, sorry! and may be more money - OEM relay is ~$50, but NAPA one is only $9...
Parts Used:
  • Ebay OEM Style Fog Light Kit 06+ RAV4: $105 shipped, got mine from Seller:Trendgear but at least 1 other seller carries these; at least with this kit the panel switch fits perfectly into the 06+ knockout
  • Toyota Relay: P/N 90080-87026, got it for $48.50 shipped from Greentree Toyota in CT
    OR get a compatible relay for about $8 from NAPA Auto Parts Store, part # is AR614 - thanks to Bigal8553 for this find!
  • Misc: Wire Tap Splice(s) and other wiring tools, 10mm socket & ratchet, screwdriver, etc.
Electronics:

> Disconnect the battery - i'm told that's important when installing the relay.
> Remove the instrument lower panel (undo 2 screws and pull), fuse box cover, then the steering column lower cover. be careful removing the steering column cover, as the clips can break easily.

> While you're down there, check the instrument panel fuse box to make sure you already have a 15amp fuse in spot #12, marked "FR FOG 15 A"
> insert the new relay:
before:

After:

> Locate the wiring harness for the headlight/turn signal lever, found on the left side of the steering column. when this line is connected to a ground, the fogs are turned on. the line is at pin 4 and is a grey wire.

> Note: with my ebay fog kit, an OEM style knockout fog switch was included. you can use any automotive switch you want to. mine included an indicator light, which i wired similarly to the euro instructions, which produced a dim light similar to the window control lights. since this OEM method utilizes the fog indicator in the gauge panel, this is not a major issue.

On my ebay switch, it seems the 2 red leads were wired together as ground, the yellow was the main circuit (which got wired into the harness) and the black was for the switch illumination. lie your switch on it's side with the harness connected and see if your scheme matches:

> To prep the switch harness for use, remove the wire loom and cut the wires about 2-3 feet from the switch connector, making sure to cut past the point at which the 2 red wires are spliced together.

> Tap into the grey fog wire with a Tap Splice, a red 22-18 AWG is best, and insert one end of your fog on/off switch to the circuit. (if your ebay wiring is like mine, this will be the Red wire on the end of the connector.) make sure to zip-tie and secure the wiring cleanly along the OEM wiring path.

> Connect the other lead from the switch to a good ground point. (if your ebay wiring is like mine, this will be the Yellow wire.) there's a good grounding spot to the bottom left of the driver's foot-well, just use a self-tapping screw.

> If your switch has an illumination light like the ebay, splice the illumination wire into the Green wire on the back of the dash dimmer knockout switch. (if your ebay wiring is like mine, this will be the remaining black wire.)

> Install switch in dash and reinstall the previously removed panels.

At this point you have a complete OEM fog wiring setup! if you wanted to slap bulbs on the OEM wiring and reconnect the battery to test, it should all work.

Physical Install:

> Pop and prop the hood, and remove this thing - what is it called? You can use a flat head instead of the special tool for the 1 fastener, the other 8 come out real easy...


> Unscrew the 2 rubber-shielded bolts and 1 fastener at the top of the front end:


> To be safe you may want to use painters tape or similar to protect from scratches as shown. after removing the side fasteners, push back the wheel well pieces to reveal the 10mm bolt (on each side) holding the sides to the top (which were not in the European instructions )


> Undo the 8 bottom bolts with your 10mm socket, noting for later that the 2 outermost bolts are longer (something i of course didn't notice until later):


> Carefully unclip the front end at the side panels and remove the front end, being cautious not to scratch at the sides. it can be done by 1 person without issue. make sure to set it down somewhere it won't get scratched!





> Remove the 3 10mm bolts holding in each fog blank:




> Add the fog light brackets and bolt them in:


> Add the fog lights by sliding the tabs in the inner side and screwing them in at the outer side, as shown. mine had no pre-drilled holes but the screws self-tapped - don't over-tighten!


> Unwrap the factory fog light wiring:


> Make sure the H11 bulbs are installed in the fog light housings, bring the front end close to the vehicle, and connect the OEM fog light wiring.

> Connect the battery and make sure your fogs work! remember to turn on your low beams, then check your on/off functionality.

> If everything works, put the front end back in place, snap in the sides, and replace the top fasteners.

> I have not tested this for sure, but this is probably the point at which you want to check the aim of the fogs. (mine are unintentionally aimed upwards as of the install, i have yet to aim them) turn the adjustment screw clockwise to aim higher, counter-clockwise to lower:


>I'm guessing i'll have to find a right-angle phillips head or try a stubby screwdriver...

> Re-attach the remaining bolts, fasteners, etc. by reversing the removal steps.

I think that's it! please, i appreciate any comments / corrections / refinements anyone has for this write-up!

Thanks!

EDITED 11/25/08: updated wiring recommendations based on RUV's research/discoveries - thanks!

This is a truly excellent write up. Thank you very much! Do you also have pictures of things are connected on the front of the car? (the lights themselves)

Thanks again!!!

yes, that's the next step, the physical install write-up; the wiring is hanging there ready to be used...

Note: Australian RAV4 CV models do not contain the wiring harness so connection is not as easy.

This is a TRULY fantastic explanation on how to do it. (but I must confess it scared the sh... out of me, I would not dare remove all of the bumper cover like this, but I am probably a big chicken!!!

You are able to just remove the lower outside 10mm bolts and pull the wheel arch plastics back out the way. Whilst you are lying down u can access the adjustment screw with ur finger as u dont require a screwdriver. You can even reach and complete the whole swap over of the lights this way, as i did.

I would like to have a separate switch and have the lights trun off when the engine is turned off (in case I forget to turn them off).

RiVot,

Thanks a bunch for the detailed install.

A couple of things, I did a little resurch and I bought from NAPA AR614 Relay for 8.00 w/ Tax.

I put the red leads to the 4 (gray) lead and black to ground.

I also noticed that the factory idiot light comes on by the speedometer which is great.

The only thing I cannot figure out is the yellow lead and I do not have any illumination on my switch.

Tried different things but could not get to illuminate.

Do you have any suggestions?

Again Thanks

Alan
