Yes, 2013 - 2015 MT & AT cars use the same engine harness. The bulkhead harness is different, but the actual engine harness is the same.

On this same topic I just had to put in a junkyard engine into my manual FRS. There is one open coolant inlet/outlet on the back top of the block which I'm pretty sure wasn't on my old motor. Discovered it when adding coolant and water started pouring out. Is this a water line for the automatic transmission cooler?

The weird thing is that the car runs fine and there is a block off plate on the passenger side cylinder head. Maybe someone already did this swap?

Can I just cap off this inlet/outlet if it is indeed for the automatic transmission?

Should've read this thread more carefully as it is explained in post #26. Looks like someone put an auto coolant crossover pipe on this engine for some reason. I'm just going to cap it off for now.

Hey,

So did you use the same engine harness? PnP? Are the engine harnesses same for both MT & AT throughout the years?

I need to replace my engine harness for 2013 AT GT86

Anyone have any idea how to remove the dowel pins off the vacuum pump location?

Indeed vice grips and wd40 worked pretty good.
