We're using a Motec M150 so it's obviously plug and play inside the car, but need to repin the new engine loom into the AC1 connector

Thanks in advance

I have the BRZ manual but it doesn't make it easy to understand. Just want to see if the above list is correct

This is the route I'm going also, and still figuring it all out.

Surely someone running a Motec has this sorted by now?

Are you trying to figure out the conversion? I'll have a pinout I'm a week about.

Yeah basically just trying to confirm what the pins on the AC1 connector are so that we can repin our new engine loom for the V8. Then the Motec does the rest

See attached BRZ wiring diagram 2013


open in Adobe then search for "AC1" be able to check that list fairly easily, just step through each match

As above, I have that wiring manual but I'm not too clued up as to what I'm looking at

Things here are pretty light so went though that list as I'll need to pull most of that stuff out. Looks OK to me.


As mentioned above, open it and search on 'AC'. It'll go pin by pin through all of the diagrams. Once you spend a few minutes looking at them,,, they are easy to read.


You can see I circled in purple 26, 15, 13, 2 and 5. You can see below that these are all Camshaft VVT signals.
