Newbie question: what is wrong with running the stock VE loom and leaving the ECU somewhere nice in the front of the engine bay? I presume GM did that for a reason.

Space? Convenience? Protection from the elements? Heat?

Otherwise, I struggle to see why the standard loom couldn't be used, and a 'simple' extension made from where the VE loom would normally terminate to an alternate location for the ECU. Is the extra length going to affect the ecu operation perhaps? Or is it just 'untidy'? And/or is my assumption that this is simple wrong? Male 'lots-of-pins-squarish' connector to female 'lots-of-pins-squarish' connector with 20-odd wires in between. Solder that up while watching a top-gear episode.
