Wiring help 97 legacy obd2
hi all, I have a harness and ecu from a 97 legacy gt auto and installing it in my 67 vw bus. I have 98% of the harness complete but Im curious on the
(fuel tank pressure sensor, fuel temp sensor, fuel level) these go to the ecu but how do I simulate them? Any help would be greatly appreciated..
Thank you for your time

The fuel temp and level will be a resistance, so for the purpose of keeping the ECU healthy, do you have a workshop manual for the 97legacy, if its
got the resitance values, go halfway and put a resistor in there.
The pressure sensor will be a voltage, maybe find what voltage input to the ECU it should be at atmospheric pressure and experiement by putting a
resistor to ground until you get around the right voltage.
I'm not up on the legacy's but if its OBDII I'm wondering if the ECU is flashable, in which case you could just disable the inputs using the
romraider software. Have you got a photo of the ECU?
