Hi i have a big/small gauge cluster problem.
My problem is that everything is wrong.
When i am driving 70mph my cluster says 60mph.
And the rpm gauge says at 60mph the car is at 4'000rpm.
Remember that the i am really going 70mph when i say 60mph.
oh and my gas gauge doesn't work either.
so can someone tell me what is going on.and how to fix the problem.

 

buy a new cluster


have you tried plugging in a different one to see if its the sensors or the cluster itself?

 

it is a new cluster.

 

First of all, what year and model do you have? I believe certain years cannot be interchanged. Also, if you have an sc300 and use an sc400 cluster (or vice versa), it would throw off your rpms and speed.

 

it a 92sc300.

 

if i were to buy a new cluster for it where would i buy one at.

 

A brand new one? Probably not worth it. Give user aliga on this forum a pm and I'm sure he can get you a 92-94 cluster.

 

ok thanks.and what about the gas gauge.

 

My gas guage was wrong too in my old SC I bought a new cluster for it and the guage worked properly. With your current gas guage the little square orange light will still read correctly when you are low on gas.

 

you probably have a sc400 cluster in your car
