Hi Hissin
You need to supply power to the PCM and to the coils and injectors. To do this you need to break into the particular wires in the harness.

You need a wiring diagram for your particular motor harness, there a number of guys on the forum (including myself) who can forward these just let us know what motor you are running.

Do you have a harness that has all the relays and fuses for the for the starter, fuel pump, coil and ignition functions already or do you need one made.
Here also guys can lend a hand, either getting one through sideshow (who will soon pop up) or buying a ready made one from the many suppliers around.

It is a great feeling to see/hear the motor start after you have done all the wiring yourself.

Cheers
Bruce
