Re: 91-92 Gauge Cluster
What are you doing with the speedo? It's electronic so there's no digital converter box needed like with the cable driven speedos.
Myself and others have done simple things like put LED's in the back lighting (mine are red), and colored the needles. I used a red sharpie on my needles.

Re: 91-92 Gauge Cluster
I bought the car with the LSx/T56 swap done and the speedo doesn't work - plus the gauge cluster just seems dated and dim.
What's required to get the speedo working, and do you have any pictures of guages with LED's? A little freshing up may be all the Dr ordered.
Thanks!

Carbon Fiber vinyl is a relatively quick and cheap way to change it up a bit.
From taking apart dash, applying and cutting the vinyl, to putting it all back together again took just over an hour.

Got to give it to you Cale Sahl, that looks great. Any pictures of it in the car?

Re: 91-92 Gauge Cluster
Is the car originally TPI/V6 or TBI? The speedos are ran differently between them. If it is originally TBI then probably what the issue is, is that the speedo buffer box hasn't been bypassed. Under the dash on the passenger side there is a plastic box, black I think, sorta by where the hvac ducting and ECM were originally. There are two brown wires on pins C and F (pretty sure those are the pins but not sure). You need to cut those two wires and splice them together so they bypass the box. Speedo should work then provided the wiring was done right and there are no blown fuses.
Re: 91-92 Gauge Cluster
The car was originally a 5.0, 5 speed car. Now has a computer out of a 2002 TA with the LS/T56.
All the other gauges work, tach etc. So I find this buffer box and splice two wire to bi-pass it?
Who would have guessed.
Thanks

Was it originally TBI or TPI? (RS or Z28??)
That will tell you if what I said will *probably* fix it.

First place I would look is to see if there are any blown fuses under the dash on the driver side. There should be one that powers the speedo if memory serves me.
