Of all the thing that I was wording. Why can't any one in here help me with this little thing that I wan having on wiring my car, all I want to know was how to hook up you rpm gauge to. I try to used the EUC wire but it won't work. CAn you hook it the the 1st coil from the motor. That all I want to as and NO one in here sent to care about.

 

Your stock RPM gauge (tachometer) in your gauge cluster? If you have an 89-90 240, and do the SR swap, it's not going to work unless you swap to the 91-94 cluster or use the SR tach.

 

I know that the 89 cluster does not work. What I want to hook up is my 5" tach. Is there a way to do that on my SR.
