the A/C relay and fuel pump relay on the EVO 7 ECU

pin 8 and 22

i want to know what type of output those wires are?

because i couldnt find any continuity to earth or any kind of switched feed across them

Bare in mind that relays etc are inputs to an ECU :confused: so not always easy to check ;)

Most circuits comprise an ignition switched 12V supply to the "relay", then to the ECU which switches the signal to ground via a "transistor"
