plug in carpet under dash?

[QuantumSyncro]

Hey
Without scrounging through the wiring diagrams trying to find this does anyone know what the purpose of the four spade plug coming through the carpet directly under the dash on the trans tunnel? I assume it's for something (AC?) that I don't have??

Reason I ask is I have a 'ghost' e-brake light I can't find the solution for and just want to verify that this isn't a connector for that.

thx

That connector is for the rear speakers. If you're e-brake light isn't coming on it's most likely a bad LED in the cluster. The e-brake and seatbelt warning lights are usually the first to die

Thanks
The PO wired around the original speaker wires with aftermarket wire so that explains why there's no connector.

The problem with the e-brake light is that it's 'on' all the time even when the brake is off, and when you set the e-brake the light gets brighter...so there's something fubar somewhere.

I think we have a gremlin in common.
Brake light on the dash glows dim.
Pulling the ebrake makes the light brighter.

My high beam indicator isn't working.

Nor is my gas gauge.

These all seem to pass through the "big" connector T14 on the back of the cluster.
It seems most of the other circuits that pass through that connector are working...

Hoping it is just loose...

That's exactly the behavior mine exhibits. I checked the brake fluid level sender to make sure that wasn't causing the problem and it isn't.

I will check the cluster connector but I had this out recently to convert it to diesel (glow plug light instead of OXS sensor light) and I was sure that it was fully connected when going in.

Since I'll be converting to a full mk2 diesel cluster in the future (adding diesel tach) I'll see if that connector is loose.

Mine was working fine til I tried to take it out to change the bulbs...
Making another attempt if I get time on the weekend.

As an electrical kind of guy, that sounds like a bad ground or a short

[voxwagen88]

In my case it turned out there were was damage to some traces on the green floppy circuit "board".
New Cluster Time.

I have to pull mine again anyway so I'll take a closer look at the circuits. I've had mine apart already to make modifications for the diesel GP light and to adapt the diesel clock / fuel gauge.

I've been wanting to adapt a Mk2 diesel cluster with tach for a while now, we'll see if I can get that done.

Which cluster do you have....with or without tach?

steve

[voxwagen88]

With Tach.

For what it's worth, VW is still clearancing instrument cluster circuit boards. ~$10

It has the provisions for the LCD clock as well.

Do you know if that circuit board they're selling has the OXS led connection?

Do you have a picture of your circuit board? Here's the one I just got for comparison:




It says 307 919 059.7 on a sticker, and 890 505 016 on the board itself. It also says 910 on it.

Sorry, I don't have a pic of it. I should have taken one when I took it out before but didn't think of it. I do know that the OXS LED connector is the center one that isn't installed on your new circuit board.

The reason I need it is cuz of the glow plug indicator for the diesel, which is in the center position on early mk2 cars. On the Fox the lower group of LED's isn't available. Only the early BX clusters with the OXS LED connector can work for my application. I do like the idea of the digital clock, that would free up the clock space for a diesel tachometer except that the only mk2 tach that could work in the BX cluster has both temp and fuel gauges....and those aren't the same shape as those in the BX and hence they won't connect to the circuit board properly.

I'll take a pic of my circuit board the next time I have it out, I need to take it out to try and fix the phantom brake like problem.

thx

ahh I don't have the board handy right now, but I'm imagining that all the traces are there and you'd only need to solder / conductive glue the bits on to be able to use it.

similar to what can be done with the analog clock clusters to create provisions for the digital one.


or maybe going 16vvincent's route and adapting the harness to work with an a2 cluster straight up.

Yeah, I've thought about going that route.

That's likely what I'll end up doing, just adapting the Mk2 diesel cluster with tach to the BX. I'd like to do it without destroying the harness if possible. I'd really like to build an adapter that I can just insert between the Mk2 cluster and the BX harness. I have the cluster connectors already, I just need to find / build ends that connect to the harness.

thx
