While swapping the motor in my 1998 M6 i have came to the conclusion that the harness is just butchered and is just plain ugly.... The guy before me had the harness repined and all that bs for a 99-02 ecu.. and there's just nasty solder points everywhere with butt connectors and so on... and refurbishment of it is just out of the question.

So... my question.... is.. What is a reliable and user friendly way about getting a new harness and computer?

Stock harness and ecu?
Fast Xfi?
Holley Efi?

If theres anymore options other than these mentioned please share. This is the only thing holding me back from starting this beast up and breaking it in for boost.

I appreciate yalls input.
