ive just bought a s5 13bt full bridge engine to go into my s4 gt-limited turbo 7. im gonna run a microtech ecu. and the s5 engine loom. what could possibly be incompatible? please dont link to the resurrection write up. its all about na to turbo so not applicable

 

it will drop in fine. only problem will be water house routing with the waterpumps. thats about it.

 

is there anything on the body loom that goes to the engine that may cause issue? or is it purely for lights etc.isnt there sensors and what not on that side?
