I just purchased a 92 240sx yesterday, and the tach and the temp gauges do not work, the car has a sr20det engine swap.
I was thinking of just replacing the gauge cluster, if anyone has any idea of why it does not work, as I am new to nissan's and was a honda person who swapped a crx.

 

sounds like they didnt properly wire the dash connector. temp gauge is a blue with black stripe, tach is yellow with red stripe (i think) the plug is a few inches from the ECU.

 

So, i should check the wiring where?
Behind the gauge cluster?
And do I have to run some wires from the ecu?
Thanks, ill be taking the cluster out tomarrow, because the previous owner has white face gauge overlays on it.
So I can take em out lol.

 

Also, where's the ecu located in the car?

 

wow... under the kickpanel on the passenger side.

the tach should work because its a 92.. something is wired incorrectly, same with the temp sensor. check wiring, fuses, ecu, temp sender etc

 

Well sorrrrrrrrry for not knowing everything, I know honda's, you need to know something, ask, that's why I'm here. To learn.
Just got into the nissan game, and now im trying to learn.

Where is the temp sensor located?

 

Anyone have any idea's?
I know the car used to be an automatic and it was swapped over when the sr20 was put in.
I'd like to get these gauges working asap.
Thanks
