Hi I am transplanting a Volvo 740 GLE B230E Uk spec with the mechanical EZ-K fuel injection into a 1929 Pontiac and i,m looking for an engine wiring diagram for this engine my main issue is I seem to have sorted most but I can’t sort out the trigger wire for the coil I have a heavy blue and a red/ white wire which I presumed were blue pos and red white on neg but I’ve found picture of both the blue and red/white wires on the same poss terminal and a thin white wire going to the negative but the donor car is long gone . Any help would be greatly appreciated
