I picked up a 94 sc300 cluster for a great price, but i have a 92 sc400. I know there are some issues with the tach. I have been doing my research and i found out that a ressiter need to be eather changed or overidden. But problem is i dont know what the hell it is..lol. Also my car has a auto trans and when i push on the buttom to place it in gear, as soon as i push it the climate control shuts off. That started with this cluster. Does that ressistor cause that too? In my research i found alot of people talking about it but, yet im too stupid to understand. Maybe, just maybe there is some one here to can make a dumb man understand.. please help.

 

No the resistor trick was for boosted cars. You can alter it SOME, but you are going the wrong direction. From a 400 to a 300 would be easier.

 

What would be your advise. Just sell the sc300 cluster and buy a sc400?

 

It's not really ever going to be right if it isn't the proper cluster.

 

Well, i guess ill put it up for sale. As low of a price as i got it i may make a profit on it.

 

There is no reason it shouldn't work. i have a SC400 cluster in my 300.

Just change out the tachometer and possibly the backplate (the plastic piece with the actual numbers on it) because the SC400 has more lights available, and it should work like stock.

You don't need to jump any resistors, as the circuit boards are identical between the two cars. the tach itself work differently. All other gauges should be fine.

 

Yes, i have heard that. But i heard that it becomes a problem when you take a 300 cluster and install it on a 400.

 

I'll try to see if i can i dentigy the plate and try it.

 

If you swap out the tach, everything should work fine.

 

kool! im going to try it prabably tomorrow night and i will let ya know. Now i have a question. I know that if i take off the needles it will atomaticly decalibrate them. How do i calibrate the back to oem standards?

 

Did you take the cluster apart yet? If not then I want to buy it if all 4 needles function..let me know.

 

Yea, all the needles work, but i guess they have to be calibrated now sence the cluster has been running on my sc400. Are in Dallas?

 

oh, to answer your questino.. No, i have not taken apart yet.

 

Oh i just noticed that you are from florida. I have never sold anything to any one out side of dallas. I would not know the first thing to do.
