FOXBODY CLUSTER F**K / Common Cluster Issues And LED Install 

I was going to ask if BREW2L has done a video on the foglight issue and potential fixes. I have this problem on my 87 GT, and have burned up a number of switches over the years. I know there are some fixes that people have done to alleviate the problem of too much current going through the wiring. Would switching to LED's in the fogs and headlights fix this issue without having to rewire or do any of the fixes that people have come up with for this problem? I like to run my foglights, as I think it's a good look on my GT.

@@dougfa3515 im sure it wouldnt hurt, hiding a relay is rather easy and maybe a 10 min fix with no major wiring to do

It’s a great mod for sure 👍

Appreciate that Jody 🤟

Great idea 💡 👌

Thanks! DemonFox is the man 💪

The LOUD flasher relay they had at the store helped a lot.

@@LiquidSSSnake I used to have an Alpine Stereo system. I wanted to hear the stereo with the top down at 70 mph.LOL. Crack heads stole the amps and the equalizer.

Thanks brother, good tip on the armor all 👍

☝️😂🙏

Great tip! I didn’t know that 🤟

The green/red wire of the alternator is activated by the resistance of that circuit. Alternatively, a resistor ~510-560 ohms across that circuit will activate the alternator, regardless of the bulb.

How would a bulb effect your battery, alternator etc??

@@williamjones8283 I think it’s one of those myths that circulate like the voltage on the TPS sensor.

@@joel4210 it uses the load of the bulb to turn the alternator on, led = minimal load and the alternator wont charge

Don't see them that often anymore

Mine says 160 also but says Ford Motorsports under speedometer.

I've got a 93 reef blue SSP. Police cars got 160 Mph speedometers. Saleen had 180 and 200 Mph speedometers.

Appreciate that! GO DAWGS 💪

No clue on that. But they work for under hood lighting and tag lights also 👍

@@BREW2LFOXBODY thanks 👌

my 84 fog light already run with park lights and highbeams. it depends on what state the car was made for back in the 80's different states had different laws about what lights can run at night. in my state nc maximum of 4 light could run at one time on front of car so highbeams would turn off fog lights. my car was originally sold in Illinois so my fogs stay on with highbeams.

@@joshruby 87-93 GT's were all wired so that the fogs only worked with the low beam headlights,as a safety precaution. To my knowledge the only differences between Mustangs mass sold in the States were California emissions cars. As an autoworker,I can tell you it'd be very cost prohibitive to cater each car to each state,it just doesn't work that way. My 84',the fog lights had been deleted,and I can't recall on my 86' but I'd bet there's a good chance the 86 and prior may preformed as you mention,or the previous owner modified the circuit to get the unlimited use of the fogs. A lot changed in 87 with the full update. I live in Illinois,the fogs working with parks & highs is not a thing. As Brew mentioned,those switches flow alot of current,in fact more than they were designed for. 87'93 gt light switches are known to fail from regular use. They'd have never lasted wired as you suggest,people use to jump wires to make it happen,ultimately causing failure even fastest. Thankfully some smarter folks figured out relays were the way to properly accomplish what you describe. I checked out the videos of your 84',beautiful car,and love the louvers!!

Hi, do you know of a video where it shows how to do the relays on the headlights and foglighta

Bebo Gc I don’t think there was a video. It was a website. I’ll see if I can post it

Anytime brother

More than likely it’s just a bad connection with the bulb. I had to take mine back out and clean some connections to get one to work. Also the dimmer could be the issue. I think it’s down toward the bottom in the center. Just pull a build out and shine a flashlight through the back to see what lights up on the front side.

@@BREW2LFOXBODY thank you. Very informative channel.

I think the white face gauges are just stick on.. you may be able to remove them.

Maybe speedometer cable

I think it's more of the cable. I am replacing mine on my build because it was making a rattle type noise and was bouncing some. As we pulled the cable out both myself and the guy doing my engine stuff got stabbed in the hand because the cable was coming apart.

Did you figure out what the issue was? I have the same problem. No instrument lights. They worked when I took it apart

@@thegeneticmachine270 Yes I figured it out went to LMR bought a new housing and switch for the light and fog light clean the dimmer and it works the gray housing was burned in the black pin hole horn still not working Nore the cigarette lighter

It could be an interference issue or the gauge itself could be the problem

Got one currently that does the same thing, also the volt meter ticks downward when the car is running. I have no idea why either.

Hey did u ever figure out this problem with the temp and the lights my 91lx doing the same thing

@@craigknatt5287 I haven't had a fox body in a decade. One theory I have is that something between the laminate in the flexible PCB degrades over time. Then voltage jumps between circuits, especially with the high resistance of light bulbs. Sometimes I wonder if splicing the harness and up the gauges directly as if they were aftermarket would work. If I get another one I'd splurge on the LMR OEM look digital gauge cluster, it solves so many issues.

It depends on what gears came in the car. But probably a 3:55 or 3:73

My 86 has 3.73 and it was 20 off so my guess is 3.55s but like he said depends what it was originally. You can check gears by how many times driveshaft turns compared to one revolution of the wheel, 3 1/2 ds to 1 wheel 3.55 etc.

If speedo is off check the speedometer gear at the transmission. They made different color gears to correct speedo.

🏃💨

Did you figure out the issue? My cluster lights worked when I took it apart, now they won’t come on. Everything else works. Checked fuses, replaced dimmer switch, replaced headlight switch and new harness.

Sounds like the float arm on the sending unit is bent.

Thanks for the fast feed back ill check into it thanks and great videos I enjoy watching them

Check the plugs on the sending unit

I was curious too as they look pretty bright

The plug or the back of the cluster?

BREW2L I think he’s talking about the parts that the screws go through. On the cluster side.

The black housing

I had to put some clips. To make it stay

BREW2L I know LMR sells a kit but I don’t know if that will work

You ain’t calling shit out over here buddy...

Lol is something that happens to most eventually 🇺🇸🔧🚘👍🇺🇸
