hey guys

I have pulled my long term fd out of storage as I have a supercharged quad rotor Fd build for a customer and part of the deal was I kept the driveline out of his s8 fd (mine is s6). Ive had a mechanic swap everything needed into my car, he dropped the complete subframe with engine loom still plugged to motor. The mechanic then took the complete engine bay harness aswell and fitted it all back into my car. The car has power at the main fuse blocks in the engine bay but isn't getting power to the fuse box under dash. Ive had 2 mechanics and another auto sparkie have a look for me but are throwing some pretty wild ideas out there and have struggled before giving up. Is there anything obvious we are missing? the car it come out of was running fine the day before the engine was removed haha. I have searched and found pretty similar posts but not the same as my issue. I will get another sparkie to have a look but at the moment I want to try and wrap my head around it before paying another guy to stand around scratching his head

Thanks in advance

Dean
