172 cup, Impreza P1
Not sure if anyone will know the answer to this but here goes.
I'm running an Adaptronic ecu and have the switched live coming from pin 29 from the stock ecu. For some reason this does not seem to be giving any voltage with the ignition on. The dash is lit up and the fuel gauge goes to the correct reading so the ecu is getting power.
Checking the voltage from pin 29 to ground gives 0 volts however checking the voltage from the battery to pin 29 shows 12volts which makes me think it is going to ground which I don't think is right.
Can anyone shed any light on this? Should there be a 12v reading from this pin to ground with the ignition on and if so what would cause there not to be?
