Ean Walley turbo installation

Hi all. I'm having problems with the TVR as no spark or fuel. Discovered this wire was broken off in the plug. Would you be able to have a look at yours and tell me which pin it should be attached to. It is the lightest blue wire. The Turbo installation was done by Ean Walley. I understand that Ean sent these kits out for self installation, if so did he provide a wiring diagram.
Looks like megasquirt has been installed using part of the old 14CUX as an adapter.
cheers

Update.
Blue wire back where it belongs but not the reason for the engine not running...dead fuse.
All back singing sweetly.
