The 2 white/red wires (+B1 and +B ) can be joined together and be attached to an efi relay/ignition (these trigger the ecu to turn on). The White wire with Blue trace (next to the top white/red wire) is constant battery - Batt(wire it to a constant 12V source).
AFAIK these 3 are needed to run car. You can hook up Fuel Circuit Opening Relay (FCOR) if you wish to give a factory fuel pump trigger, but its not needed.
BTW, it looks like a 14 Pin plug to me, so unless its not fitting somehome check pins are not bent or something....
