z32 Maf instalation

[Sleeping240]

do i need to buy the adapter for the sr20??? or??? cause it came with the wire harness.. also do i need the afc controller to actually use the z32 maf????? also i have the stock ecu

stock ECU = the z32 MAF won't work. You need a reprogrammed ECU or an AFC.
You can splice the harness yourself if you're comfortable with electronics..... but, if you have a KA, i'm not sure that the KA and SR MAF connectors are similar.
