Electrical Fog light plugs???

Espo720 · Jul 21, 2020

Hey guys my 90 lx was sort converted into a cobra by the previous owner. He slapped the gt front end on with the fogs but they don’t work.

I’ve traced everything with a test light and get juice at the plugs when the headlights and fog switches are on, but neither light comes on. I bench tested each fog and they do indeed work, so I cleaned the connections and gave em dilectric grease. Still not lighting though. Any ideas? I’ve noticed those oval plugs aren’t sold anywhere and don’t want to cut things up if I don’t have to.

Check the wires for ground

Is there a separate ground for the fogs?

General karthief · Jul 21, 2020

I don't know. Let me look.
be back in a minute

Black wire at the connector is ground, check it at the connector by the fog light

Alright will check in the am. There’s no separate pigtail that peels outta the harness for ground?

I appreciate ya checking for me, I don’t have a garage built yet at our new house so I turned the shed into a shop but don’t have power up there yet. Once it gets dark it gets difficult, we live on a mountain so its darkkkkkk

My book shows a separate ground but does not say where it is, I will look around on my gt tomorrow afternoon.

Thanks for the diagram. Popped out to check and I’ve got ground at the plugs, nothing is getting through the plug to the light though.

So you have no power at the plug?

I’ve got power at the plug on the harness side, but it doesn’t make it through the plug. The light side gets nothing on both the left and right fogs.

You have no power and ground in the socket?
Make sure the pins in the plug are making contact, probe the wires with a needle to check power/ground.

Wires probed it should all work. I made jumpers and bench tested the lights off a battery and they light right up. I’m kinda stumped. All the grounds check out, only thing I can think of is the slots on the plugs are worn enough to not make contact when plugged in.

That's what I'm guessing too, make a jumper and connect it between the plugs. Get some contact cleaner and spray the plugs.
Curious, can you make the lights blink by wiggling the plugs together?

I got those plugs just hanging there as I don't have fogs on my LX.

General karthief · Jul 22, 2020

So the fog lights (that is what you are working on right) are not mounted?

The fogs are mounted up. Are the brackets maybe self grounding? I’ve wired lights that are that way before, but figured since the diagram shows wired grounds it should be fine. Plus both of em are out at the same time.
Plugs were cleaned with QD cleaner and given a squirt of dielectric grease in each socket.

If there are two wires at the connector one will be power, one will be ground, your problem (given your description) likely is in the connector.

Yea but what are the odds both connectors are no good?

If someone had higher watt bulbs in the lights, or they were hanging open in a 5.0 LX, it’s possible. If you are sure the wiring and plug is good on the light end, I’d be considering a more universal weather resistant replacement connector pair for both sides. Be sure to skip on shrink tube, solder, then shrink the shrink tube over the solders.
