Wiring OEM fog lights and oem switch into van

[bikerjosh]

Ok, so making some progress on this project, wiring harness done, relay mounted, just need to connect the switch wiring wise.
Went to pop the new bulbs in H7 (not sure if I got that from owners manual or internet) anyway bought both a set of halogen and LED bulbs to see which I liked better. Both are too big to drop into the base for the light.

Anyone running fogs who has replaced the bulbs? If so what did you use?

I'm in the middle of cutting the outer metal flange of bulb w/dremel to get them to drop into housing. Didn't want to modify the housings as long as it took to find some.

Thanks Josh

Edit: got impatient and went ahead with it.

bulbs new, new modified, OEM



Just had to open up the housings a little.

So are the H7 bulbs the correct bulb but for some reason just too big?

How do they look?

Thank you

JDM

[bikerjosh]

That was the closest bulb I could find to the original. Look good, but yellow against the LED headlights and under the bumper LEDs. Eventually I'll try and find an LED replacement that will fit so the color temp of lights will be closer.
I'll post a pic later.-J

Forget how they look! How do they work in the legendary Californian fog?

[JDM VANMAN]

Carbonized you always have good jokes!!

But as for the bulbs (lamps- proper electrician term) which brand did you use, I was search on line and but the ones I’ve noticed aren’t of any specific name brand, for example-

and they’re cheap of a set. Being that they are 80w LED’s and the housing shows that it accommodates a 12v 35w bulb is that ok? Sorry I don’t know how all that electrical stuff works.

Thank you

Bikerjosh,

I’m just adding to your write up another option that can be used with slight modifications-



I went with these Noyka H3C Halogen Nok7659 bulbs because they seemed to be the closest to OEM with very slight modifications.








Both bulbs-
OEM is clear white 35w bulb
A/M is yellow 55w bulb






Side view




Side by side A/M bulb is fatter at the base



Housing does need slight modification, crimp the piece that’s boxed in red so the bulb can drop all the into housing.



This piece on the bulb (red box) is to small so the housing needs to be modified.



This is the OEM bulb clamped down, once the housing is modified the A/M bulb should drop in place and the clamp will hold the bulb in place even though it has a fatter base.

I just replaced my fog light bulbs and the H3C should drop right in. Do a search on eBay and you will get a handful of options.

[JDM VANMAN]

Which brand did you use? We like aftermarket first time fit and no modifications!!

JDM

[hunziker87]

As far as brand goes... China? I got them from this eBay dealer

https://m.ebay.com/itm/HALOGEN-H3C-6...-/131547822469

They were 9 bucks, fit right up and haven’t had any issues with em.

[JDM VANMAN]

Good deal on price, I paid double. They look like the same as what I got but mine aren’t seating in the housing completely without pinching the spot that’s highlighted in photo up above.

Nice job

So I removed the entire headlight assembly that holds the lights to try and remove trim ring screws with no luck. But I did find that my LE that didn’t originally come with fog lights has a pre-wired pigtail for fog-lights!!

Oh

Oh man! I hope mine has those connections when I open it up!!

[JDM VANMAN]

Oh

Oh man! I hope mine has those connections when I open it up!!

Not only do I have the pigtail wire for the fog lights but upon further inspection I found the foglight wiring relay in a cluster of relays located behind the panel that’s right above the right knee!!

You probably will... my bare bones Cargo Van has the pigtails also. As well as a relay.

Incase anyone is looking for new fog bulbs, these are a perfect fit + very bright.

Seems appropriate being the only thread, that I could find, about the fog lights on our Vans. So I have a functional pair (tested the bulb with a jumper wire, my van doesn't have the connections for foglights unfortunately) and I have a 5-pin switch from the rear defroster off of an LE van and an unknown condition relay from another van. I am assuming the job would be to simply get a suitable connector for the lights, if anyone knows of one other than a harness do let me know, tap into the fuse box and fuse it, wire it to a relay (supposedly theres already a relay meant for foglights in the vans but it is missing on those without foglights) and then the switch if I'm not wrong. Can't seem to pull a part number for the foglamp relay but maybe there is a compatible relay available? If not I have some square relays I might be able to rig up... I did test fit a foglamp to my van and it seems to line up good! IF anyone has any inputs, do tell as I would like to learn more, I will try to find an electrical diagram online somewhere for some additional help with this too.

Alright, after some digging online I found an appropriate diagram for the defogger switch. Interestingly, it doesn't show pins #1 and #2 but it does show it does have a light inside of it as I assumed. Now whether or not it's good I'll have to see. For anyone curious, here's the diagram for the switch operation:

I too have an M3 Light Control Relay (Part #: 90987-01003) I nabbed too, although I've never tested a 3-pin relay before so I'll figure out if it's any good in the first place...

According to the part #, it's a multi-use relay for the fog lights, A/C, headlights, tail lights, etc. which is good to know. One of the reasons I was severely confused looking this part up was the plug's butt connector was still stuck onto the relay pins so I was quite confused as to why my relay had only female connectors. As for testing the relay, should be straight forward now, hopefully. Looking at the butt connector, the plastic seems somewhat melted on pin #2 which is odd, might not be any good anymore then and my digging online shows some OEM ones for about ~$13/piece or some sketchy looking new ones online for a third of the price not to mention a straight month long processing!!! Anywho, I'll test it and report back today on what I find.

Relays good, now I'm onto the step of test-wiring everything together (Harbor Freight butt connectors will suffice, I'm planning to tap into the fuse box since it already has the fog light fuse anyways) which will be interesting. Consulting my new 1989 Factory Service Manual & Electrical Wiring diagrams to piece this together. Luckily I don't think I will have to pull any dashboard pieces since I can probably snake the relay into where I can put it and go from there. This'll be exciting since this will be the first time I've ever wired up anything on one of my own vehicles, let's see how it goes...

First things first, the salvaged/barely hanging on relay connector (ill take pictures tomorrow, lost daylight figuring out where is everything on my van and sizing up the components) fits questionably into my male ends, doesn't help that trying to crimp one pin down for a better connection resulted in it cracking slightly, might have to get new pins... or a new connector... and a foglight connector... or maybe a new van kidding. As for my "Fog light switch" the female ends seem to be quite cramped and I had to take some of the insulation off of one to squeeze all 3 in there.

For the obvious power routing I'll draw up a diagram from what I can condense from the factory manual in my test wiring... as always, if anyone has any input, do let me know. I'll try and use some larger gauges of wiring in advance but I'll probably need more since most of it I took from random sections of the harnesses in a 2006 Sienna. I'll attach some pictures after this post for more information surrounding the fog lights as I've found via my FSM.
