Default Fuel Pump Wiring for Megasquirt?

Hello,

Anyone have a suggestion of the best place to connect to the fuel pump wiring from inside the cockpit---or engine compartment? I think the wire is green and white.

I am installing a Megasquirt and would prefer not to wire it all the way back to the pump.

Thank you in advance.

You can run a switched or relayed 12v wire through the lid of the fuse box. Insert a flat connector where the fuel pump fuse normally goes. Thats the easiest way.

Thanks RP---did not think of that one----I guess it would be the "fuel pump sender" fuse?

Pin 4 at the rectangular connector near the diagnostic plug (engine bay) should also get you there.

This will force you to create your own wiring for the O2 sensor, which you're probably doing anyway.

The rectangular plug in the engine bay is your friend.

Read the schematics and understand the stock wiring.

Then your MS will be plug and play. There really is no need to rewire anything.

But be aware that you will be at the mercy of the DME relay.....but who doesnt carry a spare anyways.
