Z4 vs. H4 ecu...

Does anyone know if there is any pin-out difference between subaru H4 and Z4 ecus?

Just bought a Z4 to add a bit of boost to my ej20g but the car won't start..

the starter circuit works but the fuel pump is not activated... is it possible that Z4 grounds the fuelpump pin and the H4 sets it high?

all comments are welcome!!! :)
