Default HFS3 install on Mazda CX-7 (2.3T)
Hi,

Im making a big turbo build for my CX-7 (2011), and a HFS3 is part of the equation

I just got a never used HFS3 and from what I read on here, its a version 1 (blue control board, serial#10032) but it came with a version 2 ECU harness (there is a version 2 sticker on the bag of the harness)

The engine is the same as the Mazdaspeed3 (MZR Disi), but I dont think the ECU plug-in is the same (Auto tranny, AWD...)

Any help with the wiring would be greatly appreciated

Thanks
