here goes
labels wireign diagram for the ABF, stuff in green you won't need to do anythign with, that lot goes straigth from the ecu plug to ether the multiplug onthe enigne or various sensors around the engine the stuff in red boxes you'll need to do somethign with if compoent dosen't have box it is optional

pinout for the ecu, pin number function and wire colours


pinout for the engine multiplug usefull for megasquirt

the remaing wires and some info on connections sensors need
