Could anyone tell me where the RS-232 port is exactly for your gauge set up?

 

under the driver side dash

 

I'm assuming you're referring to the output of your AEM wideband/truboost. RS-232 is just a protocol for a serial wire. If you have a FIC or an EMS you can use it for data logging by using it as an input. I'm not sure how to input that wires signal into the EMS though.

 

wideband, oil pressure, boost. i didnt get an owners manual with the car (fail) so im having a hard time finding which one the port is exactly. i know its driver side. thank you for the help.
