Do you really want the Megasquirt ECU to control the fuel pump? AKAIK the stock wiring turns on the pump when the ignition is on without any input from the ECU. If you turn the ignition off whenever the engine isn't running you would be manually controlling the fuel pump just the same as the Megasquirt does.

 

If you want to find the fuel pump wire without the wiring diagram, start looking at the fuel pump for one end of it and trace it back.

 

 

Here is what I would expect based on my Australian delivered 260Z.

 

There would be two wires connected to the fuel pump.

 

One wire would go to earth which you can test for continuity to the body using a multimeter (best done with the ignition off). Its most likely black. Talking about the wiring harness side, might be another colour on the pump side of the connector. The earth wire probably splices to a few other earths and is bolted to the body somewhere in the rear hatch area near the taillights.

 

The other wire is your positive wire which runs up into the cabin, under the right front seat and splices to the main ignition power wire somewhere near the fusebox.

 

Hope that helps.
