does anyone make any ecu adapter plugs for engine swaps,just curious

 

no, but if you are doing the typical s4 T2 into s4 n/a swap you can retain your stock harness and change like two wires.

there are s5 patch harnesses available though so if you install an SAFC or something you don't have to hack up the actual engine harness.

 

You can also use a S5 N/A harness with a S5 TII.

I wish i would have known about this SAFC patch youre talking about. I still did a pretty good job on hacking my harness and sottering the NEO though.
