TT Jspec Auto / TT UK Auto ECU loom compatability

I know you can install a Jspec TT Autobox in a UK car and vice versa by changing the propshaft and Diff's etc but are the wiring looms the same between JSpec and UK?

i.e will the UK TT Autobox work fine using a Jspec TT Auto ECU?

 

Looking at the ECM Pinouts they seem to be the same.

I don't think there'll be any problems. I've done it on my 2JZ-GTE MKIII swap.

 

I'm running a 1999 Soarer gearbox on a 1993 JZA80 ECU. And before that I was running the UK spec autobox on the same JDM ECU.

 

The only thing I can think of as possibly problematic would be matching the new VVTI autobox with the old ECUs (and even that might not be a problem)
