Alexduong88 Posted January 19, 2022 Report Share Posted January 19, 2022 Looking to see if anyone know how to do wiring install for the strain gauge for the WRX104X G4X Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 19, 2022 Report Share Posted January 19, 2022 You will need a strain gauge with an amplifier that outputs 0-5V, you can then connect it to any analog input. Quote Link to comment Share on other sites More sharing options...
Alexduong88 Posted January 19, 2022 Author Report Share Posted January 19, 2022 Sorry New to the link ecu …..how does the analog output work is it a extra harness you need to buy to plug in? Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 19, 2022 Report Share Posted January 19, 2022 Analog input or AN Volt input is a input that is designed to take a 0-5V signal from a sensor. Things like the MAP sensor, TPS, O2 sensor etc are connected to analog inputs. You possibly have a few options to choose from: AN Volt 11 or AN Volt 12 on the expansion port - You will need to buy an expansion loom to plug into this. If the engine has had the TGV valves removed then you can use the old analog inputs for the TGV position sensors. These are AN Volt 4 or AN Volt 5, ecu pins C26 & C27. You could use the old air flow meter input - AN Volt 8, pin C23. You could use the rear 02 sensor input, AN Volt 7, pin D25. Quote Link to comment Share on other sites More sharing options...
Alexduong88 Posted January 19, 2022 Author Report Share Posted January 19, 2022 ! so with the strain gauge with a amplifier that outputs 0-5V could you use the AN Volt 11 or AN Volt 12 on the expansion port? Or would I have to find a AN with a 5v? Thank for the help Quote Link to comment Share on other sites More sharing options...

Alexduong88 Posted January 19, 2022 Author Report Share Posted January 19, 2022 Is this the expansion loom you would need to get the AN input? Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 19, 2022 Report Share Posted January 19, 2022 correct. Quote Link to comment Share on other sites More sharing options...
Alexduong88 Posted January 19, 2022 Author Report Share Posted January 19, 2022 Adamw do you know what color wires are for input like a diagram? Quote Link to comment Share on other sites More sharing options...

If you look on your ecu board it will have a print of each one of the pins and there corresponding function. Quote Link to comment Share on other sites More sharing options...
