1990 fog lights

[efnfast]

Bought a set of HID fog lights from "Vette Lights"
First it says unscrew the access panel, there is none on a 1990.
Secondly, there does not appear to be a connector close to the light. Seems like I'll have to tear half the harness apart.
Suggestions?

Steve,

The access panel is for the 91-96 bumpers. You should be able to access fogs from behind.

90 access is under hood next to the air box.. you will need to get creative to mount correctly

Thanks guys, found access to the bulbs, looks like wiring may have to be creative.

[XfireZ51]

Steve,

If these are the same as my HIDs, you should be able to adapt stick harness connector rather than just use spades and electrical tape. You need to push pins out of harness connector for use with ballast.

[efnfast]

Dom, everything is plug and play, except the weather pack is hooked to a long connector because there is no direct access to the bulb. You can't reach your fingers in far enough to twist the bulb without the extender. The OEM bulb has the weather pack plugged directly onto it, this new one does not.

[XfireZ51]

Steve,

This is the harness connector that can use the spades prongs from the kit. I was able to use the weatherpak connector from the kit and use the OEM spades going to the ballast.

[BigJohn]

I don't, on second thought I do!

👍🏿

[efnfast]

Lights are in. I had to make up a special tool to reach in and twist the bulb, there is no way to reach it with your fingers. It's almost dark here, I'll pull the car out in a bit and see if they were worth the effort. With making tools, broke the first two, I must be four hours into it. Wiring was plug and play, but the wires were short enough I did plug them in using the brail method

[efnfast]

Well, I am officially impressed. These came from Vette-lights.com.
They are a true plug and play, change the bulbs, and the ballast interupts the factory plugs with no cutting or hacking.
The only hiccup was getting the bulbs installed, a little tricky on a 90.

Glad this went relatively well, Steve.


Interesting timing in that I just finished (today) a mod to get these to work in my'91. Like several other Registry members, I could not get these to work reliably without providing power more directly to the ballasts through a relay controlled by the factory fog light circuitry. Like others that had this problem, I could get either one light or the other to come on, but not both; it was always a race as to which one would illuminate first. I looked for a bad ground as the source of the problem, but could find none. These lights are exceptional and well worth the mod.

Odd that people had this issue. Never did that come up in my install 3 years ago. They've worked great from the start.

I had this problem on my 91 as well. One light would want to dominate the other and they would rarely run in pairs.

[XfireZ51]

So mine is a late 92 car. perhaps something changed. I used the Corvette Mods kit.

[efnfast]

I've had no issues with them coming on, but as stated, installing the bulbs was a real pain.

Correct.. 91-96 are a different design. 84-90 are the first design.

I may try this on my 90 with the 91 body. I have to wait now until winter as it was 109 yesterday. Ugh. Summer is here. GC

[secondchance]

I went to HID driving/fog lights on my 94 and had no issue.
It is strange that some are finding the right and the left side fighting for juice...

Jeff,

I was thinking more along the lines of electrical updates.

[Ozruss90]

Just placed my order with vette lights. Can't wait to receive the kit and install it.

Please post up how you like them.

[efnfast]

I've got his headlight kit coming, these will go in very quickly. I've also got an interior kit coming, these may take a while to get installed.
I've currently got Sylvania ZXE H4's installed. These are much better than stock, I'll post how much better the LED's are.

Yeah Steve, I'm using the halogens for headlights altho I hardly ever use them. The fog lights work just as well if not better in an area like Chicago.
Look forward to hearing about the LEDs.

[efnfast]

Both headlights installed, true plug and play. I think these are going to be so bright I'm going to have to aim them closer to the ground, I expect complaints from other drivers.
Good problem to have. The fog lights are not co-operating with the high beams. They are going to send me some resistors to see if that solves the problem. I'll post up as soon as I have them. I'll also post on how they do. Problem is it's summer and I'm in bed before it gets dark. - Steve

[-=Jeff=-]

Let us know how it goes with the fog lights. Which headlights did you get again?

VetteLights.com. Unavailable right now. Prototypes. I think they will be available very soon.

Domenic, who's fog lights are you running?

Can you post some picture of the lights? More of what they look like not necessarily the light projection

[efnfast]

If I text them to you , can you post them? I ain't that smart.
Just came back from a late night run (at least for me). Way bright.
No complaints from other drives. Although, the cops might have turned around after me.

[-=Jeff=-]

Yes I will pm my #

Thanks for posting those for me Jeff.
The fogs need ballasts (included).
That is my patent pending installation tool for 90's. The 90's do not have the drop down door.
When I installed the fog lights, you could barely tell when I turned on the Sylvania's.
I had/have Hella housings for H4 headlight bulbs. The LED's fit right in. I dabbed a bit of silicon on some of the holes, as the dust covers won't go back on. Looking around the housings and buckets, it didn't look like dust or water was going to be a major concern.
I'll continue with the thread after I get the resistors to see if that fixes the high beam issue.
Did I mention that the fog lights and high beams are not cooperating?

[-=Jeff=-]

I have a fix I need to test out for the fog light/ High beam..

the 1990 should have a relay under the Pass side hush panel.. after finding that relay and using a Standard Automotive 5 terminal relay

New relay will have 5 terminals
85 - Coil
86 - Coil
30 - common for switch
87 - N.O. Contact
87a - N.C. Contact

One added relay:

Cut Lt Grn on OEM relay, or you can try to remove pin
Non-relay side (High beam Power) of Lt Grn to Pin 86 of Relay
Pin 85 and Pin 30 of relay to Ground (New Wire)
fog light side of LT Grn (OEM Relay Side of cut wire) to 87a.


I am looking at a 1991 page on the Service manual, so the 1990 might be different since 90 is a very odd set-up.

This should allow the Fog Lights to work as they were with OEM lighting..

My next challenge is to get front Parking/Turn LEDs to work when parking lights are on, without using Resistors

[efnfast]

Jeff, so will this relay replace the original?

[-=Jeff=-]

Jeff, so will this relay replace the original?

No it is an addition to what is there. Like I said I have not tried it yet, but theoretically is should work

[efnfast]

Do you not like the idea of the resistors?

[-=Jeff=-]

I don't. They get hot and if I am going to LED or anything new, I would rather find another way than add Resistors.. You can use them, there is no problem, I just prefer not to if I can help it

[BigJohn]

Roof mounted?

[efnfast]

Four of these lights on the roof would be the nuts!

The fog lights are not co-operating with the high beams.
- Steve

This is what I did. It worked.

[efnfast]

Excellent. I didn't read it all the way through, are you using the external light bulb as a resister?

[secondchance]

Simplest solution I found and used on Jagdpanzer's 94 was to remove fog light relay, locate and bend the ground post so that it will not plug in and complete the circuit, solder electrical wire to the bent ground post and ground the other end of new wire to one of the bolts under the passenger side structure. If you ever want to go back to original wiring ( don't know why but...), just replace the fog light relay with a new one.
