930 tahometer
hi guys
i am in the middle of conversion SC to turbo and I want to install 930 tachometer in order to make it look OEM . i install the gauge i even bought the correct sensor and yet it does not work.
as i understand from the web there is a relay in between the parts is that truth?
does any one have the correct wiring or any knowledge how to make it work do i need to add more parts.
did any one did it ?

You need to find the pin out to the tach for the boost gauge. If you are doing a conversion you will have to run an additional line to the rear boost sensor and attach it to the tach. The sensor is ground based and as the resistance deviates the gauge will correspond with the correct reading. You can't just plug the tach in and assume it will read because the SC didn't have the control line for the boost sensor as it didn't need it. It's an easy job, couple of hours at most.
