Fitting Z32 maf to '96 classic ?
I've just bought a Z32 maf off ebay complete with the wiring and plug.
Can anyone tell me how to wire it up to a '96 wrx ?

Z32 connector has 6 pins labelled A to F:
A - Not connected
B - MAF Output Signal
C - Gnd
D - Gnd
E - +12V
F - Not connected
Subaru 92-96 MAF Connector has 5 pins:
1 - +12V
2 - Gnd
3 - Sensor Gnd
4 - MAF Signal
5 - Not connected
just make sure you keep the gnds separate.. if the gnds in the wiring loom are connected the powerfc won't power up.. check immobiliser anyone

personnaly I prefer to leave the original plug on and solder into the loom so you can switch between them if you ever need to refit original maf.. but yes you could just cut it off and solder the new one on

The Z32 maf will support a higher power output than the standard unit...You will need either a remap ala ESL or similar (Simon can sort you out there) or an Apexi Power FC....

By "leave the original plug on and solder into the loom" do you mean that I will have 2 plugs then. The original one and the plug for the Z32 ?

yes.. then you can continue using the car on the original.. switch within 2minutes to map it etc.. and then if you sell the car and want to return it to standard it is an easy plug and play..

Had a chat with my teccy today re this...Every STi4 maf we have modded to fit an early classic has been wired with the earths joined all with no issues..Probably haven't done as many as yourself but haven't found one yet that wouldn't run when wired this way....
