I was referring to a step by step on Pirate 4x4. Here is a link to the picture:

And what he said:

This circuit is four wires:
black plug pin C to ECM pin B7
blue plug pin E to knock sensor
brown plug pin D to ECM pin D1 and to a ground lug
pink/green plug pin B to +12V (see note above)

I will check out the FAQ for the relay info. Thanks.
