mercedes 190e 5.5 v8 engine swap help

[mattspik949]

Hey I got a few questions about swapping 2008 mercedes s550 engine into 190e.
I already have the complete engine and transmission swap with both computers harness lines etc complete pull out from crashed car. Transmission is 7 speed auto. I am not afraid of installing the engine just the electronic side of it. Transmission has no shifter computer does it all
Do you guys know any place that could help me getting the harness customized??
I am really happy about the engine that I got. 382hp moves s550 (4200pounds) 0-60 in 5.4 sec!!
Thanks
