Rear Foglights - better integration

Relay needs installing in the factory socket,  passenger side footwell. Fuse is usually fitted, drivers side footwell.

 

You can use the existing socket located on the sonar sensor loom on the driver's side ( photos of all this is available on previous posts) 

 

You can add two pins to the existing socket ( the side that attachs to the fog lamp, both the male and female sides were present on 3 alphards i have done, so just add two pins from summer other cheap connector from eBay) 

 

I agree, the oem rear fog looks naff, but I'm sure it's actually the entire quarter panel that attaches to the rest bumper, so it's cost will be greater than valenti.

 

Edit. I was wrong about the quarter panel it seems, maybe I'm mixing it up with 10 series winter kit fog

 

Hey Chris, thanks for the message. This is what puzzles me (and I guess I'll find out when the car arrives) because I am hearing that on 20 series relay is already there (I bought one anyway just in case). Was relay not present on your 20 series? Also, I am installing the stalk and people advise that if you're using the stalk then relay wasn't required whereas if you're adding some button in the blank space then yes, relay may need to be installed.

 

I am planning to use the existing socket, as seen in your picture on page 4, as it is specifically designed for OEM fog light (left blank on those vehicles that didn't opt to have it installed from factory). Do you know what connector/plug would I need to attach to this. I found the part number being 81215H and so probably this connector is right?

Just a reminder about fitting a flush fitted rear fog[s],some tow bars fit very close behind the rear valance/bumper,leaving little or no  room for the light/s

I think the plug looked a little different on mine, but Toyota nicely left both halves on the connector under the bumper. 

 

My 2009 20 series didn't have the relay fitted, but fuse was.

Cool.  Will let you all know how it goes!

 

Well I've got the LED strip now.  I bought a set of super bright 5050 LEDs ... I can get 12 in the space.  Should be able to get another  3 in ... but alas you can't cut the strip just anywhere.  I'm pretty sure 12 will be bright enough though ... am still seeing the colours in my vision from when I connected it to my battery 🤣

 

There is only one issue though.  The LEDs are too big to sit under the reflector.  I guess I could just now worry about it and get on with it ... but I'm thinking I could carve into th eplastic slightly.  Now just have to figure out how to do that ....  Any suggestions appreciated

Part number  84140-42080 - common to several high end toyotas, the standard part is 84140-42070 - the wiring loom is already set up for the rear fog, even the fuse was present - I had to add the relay in the passenger side footwell.

 

I bought part from here:

https://www.amayama.com/en/part/toyota/8414042080

 

next step is to drop bumper and connect the fogs to the existing plug that is attached to the driver side rear sonar sensor

 

Is there just a plug under the bumper waiting to be connected or do we need to join some wires, I did have a look at the wiring schematic although found it a little confusing is it easy enough to find a connector at the string wheel end to simply extend to the switch?

@Chris.ac You are a total legend! Fog light in, working on original loom with tell tale light in dash being illuminated. Thanks for all your help, really appreciate it. 

 

For anyone else looking to do this it's not that hard and you can do it without removing the steering wheel if you're not changing the stalks. 

 

All that needs removing is the cowl behind the wheel so you can get access to the lighting wiring. This needs two clips releasing that you can see once the steering wheel is rotated out of the way. Then use a trim tool to pop the two sections and drop the lower part out off the way. 

 

The lighting stalk connector has two rows of wiring, the lower row is nearly fully populated, the upper has three wires only. The rear fog one is the blue wire in that upper row nearest the steering column.

 

In the picture I've already depinned that blue wire and run a lead from it to a Toyota rear fog switch fitted to one of the blanks. The other side of that switch needs to be connected to earth. I dismantled the switch to disable the latching mechanism so it became a momentary switch like the factory stalk. 

 

Not sure why I chose that particular blank! With a relay fitted in the passenger footwell and the lights and front foglight turned on, pressing this switch makes the relay click and the tell tale light illuminated on the dash. 

 

Final step was to access the connector behind the rear bumper. Listen to what Chris said above, it's so, so much easier to remove the bumper than it seems and taking off the wind baffle is indeed no good for access. The connector fitted has the female side plugged in for you already, all you need to add is the correct pins. I forgot to photo the actual plug but it was different from the one I bought in eBay but the pins were exactly what was needed. 

 

For now, to get an MOT sorted I've fitted a round smoked LED light where the towing eye cover should be as that was missing anyway. I don't think the light will last too long, but I might get a winter if I'm lucky. I'll get the proper ones from Japan next time. 

Doesn't look terrible, but not the nicest. 

 

 

But it does light up! 

 

So thanks again to everyone, especially Chris.ac.

I see the switches seem to have four wires in what do you do with the other 3 and the original blue wire to red of the switch?

Not sure if I'm understanding you correctly. Are you referring to the aftermarket fog light switch wiring or the wiring in the stalk? 

 

Assuming you are talking about the aftermarket switch, then it needs to earth the wire I extended from the stalk connector briefly to trigger the light on or off. Most aftermarket fog light switches latch on or off, so I had to butcher mine to no longer latch so it became a momentary switch. I used a test tool to determine which off the switch wires did what. I presume they spare wires light up the switch icon when the headlights are on, something I meant to do, but have never got around to yet.

Yes there's is both a socket and matching plug tucked up below the drivers side rear lights cluster. Bumper will need removing to access.

Ok interesting so essentially with the aftermarket switch I would want a 12v for light/latch and then two grounds for each the light and the blue signal cable

Sorry, thought I'd replied on my phone, but it didn't seem to submit.

 

Not quite. There's two LEDs in most aftermarket switches, one to illuminate the fog light symbol so you can find it in the dark and one to show that the fog light is on. As I wired mine to use the in dash tell tale, I wasn't bothered about the one in the switch and I was too lazy to sort out the illumination LED too. There could be one or more earth, depends on the switch you buy.

 

As I stopped mine latching the built in tell tale wouldn't work anyway, all I wired was the wire that is actually switched to the steering wheel loom and another to earth.

If you have an etc unit in the small coin box to the right of steering wheel, you can grab an illumination and a switched live connection from the socket, it's not useful as an etc unit in the uk.

[jonnyblagwind]

From various information I've pieced  together from this thread,

 

I should 1:

 

be using the blue wire from the stalk plug in the right by the steering wheel to feed the new switch

 

2:

 

For a relay of the same type as the others under the engine bay I'm the empty slot.

 

3: 

Connect the new fog light to the spare cable in the bumper 

 

Does that all sound correct?

I have the nano switch which seems to have a light on it maybe can use that?

Not that fuse box, it's a relay in the one tucked up under the dash near the passenger door hinge area

I am getting the fog light sorted out on mine today as, when I pressed the button on the dash, the switch would light up but no new light would show on the back.

I traced the feed to a coil of wire in the top of the boot - it had never been connected to anything though it had been through several MoTs in the UK!

 

Anyway, I have ended up feeding the wire into the bumper area - currently it's connected to one of these: https://www.amazon.co.uk/dp/B082VH312R?ref=ppx_yo2ov_dt_b_fed_asin_title - which is NOT an LED and also comes with no bulb or wiring, which I am currently hanging from one of the lower bumper supports as the 'strap' between it and the bumper has been broken off.

I need to get the earth working but it will do the job of passing the MoT in April, and if I can get the LED reflectors sorted before then all the better, I can easily remove the hanging light.

I just need to find out how to get the rear reflector strips off the bumper - it looks like I can either:

  1) remove the bumper or 

  2) try and unscrew them from underneath

Which will be easier / quicker?

 

*** Update ***

Well, that could have gone better. The fog light is working at least, so I moved onto trying to get the wing-mirror auto-retract module working but in the process I seem to have killed the sunroof, indicators and radio (at least).

The whole lot is quite a tangle of extra wires accumulated over the 19 years of life it's had, as well as a very basic camper-van 'conversion' so trying to trace stuff is troublesome.

If it wasn't so cold I would still be out there.

Following with interest. What year is your car? I’m sorting my stalk and fog lamp on Monday. As previously mentioned I have a relay but mine is supposed to be located underneath the passenger footwell not in the engine bay as you showed - is this even the correct place for you? I have a 2012 facelift Alphard 3.5. 

Based on all the info I sourced, my plan was to install the stalk, possibly add the relay (many mentioned their cars already had this present) that is located underneath the passenger side footwell and then just install the fog lamp to the blank connector that is supposed to be on the right side behind the bumper using the plug connector I bought on eBay (pic below).

 

The reason I ask is because my method seems to be plug and play only.

I am thinking of modding the reflectors to add LED/COB strips - is it possible to remove them from a 2005 rear bumper by getting access from underneath or am I looking at dropping the bumper.

I already have a dashboard switch and cable in place - currently it's feeding a light on a hanger under the bumper, which doesn't work too well and looks rather naff also.

I recently finished installing the stalk, relay, and fog lights on my 2012 Alphard. I'm grateful for the help I received from the forum members—the information shared here was invaluable.

I've begun documenting all the modifications I make to my Alphard, from the day I got it to this latest fog light installation. I'm creating a video tutorial demonstrating each step of the OEM fog light retrofit (including the stalk and lamps) to simplify the process for others. This video will provide a single, easy-to-follow guide, saving others the time and effort of extensive research. Here's the first video:

What stalk did you use I've just tried an avensis but the switches ended up all messed up in how they worked had also tried a RAV4 stalk which was turning on the fog light light on the dashboard but ended up sending it back because it didn't fit on the original hole which I've ended up packing it in the second attempt with the avensis one?

I bought it directly from Japan, the below site that people on other forums/group suggested to get OEM parts:

 

https://www.amayama.com/en/genuine-catalogs/epc/toyota-japan/alphard/GGH25W/80091

 

You have to narrow your search to the exact VIN/chassis/model number of your car as I did in that link above, then you won’t have any issues.

Did this come with both parts for the left and right side of the stalk and an I correct in saying you have a 20 series ?

No, only the right side. The left side disconnects. I have a step by step video which I’ll upload shortly.

[Simbad]

Great news! My Alphard just passed its MOT. To celebrate, I've created a tutorial video on how to properly install the rear fog lamp using the OEM stalk and relay. This guide is specifically for second-gen Alphards, but based on feedback from first-gen owners, the process should be similar.

 

This project took me months of research and gathering information from various sources. Since I couldn't find a single comprehensive video covering all the steps, I decided to make one myself.

 

I hope this video is helpful to the entire Alphard community. Please like, share, and subscribe to help spread the word!
