Sup guys.

I got most of my MS wiring connected to my car. It's now down to details of things to done, then I will truely join the Megasquirt team!

But now the more I read, the more I get confused.
Look at this two links:

In http://forums.2gnt.com/dcboard.php?az=show_mesg&forum=54&topic_id=363&mesg_id=363&page= I clicked on the first Link (http://megasquirt.sourceforge.net/extra/setup-neon.html), and brought me to this wiring diagram:


And in another post: http://forums.2gnt.com/dcboard.php?az=show_mesg&forum=54&topic_id=2170&mesg_id=2170&listing_type=search
This wiring diagram is shown:


They are both said to be for 420A engine (our eclipse setup) but they are very different in 2 ways: Fuelpump control, and Pin26 usage.

I am following the 2nd diagram above, and since last weekend I finished wiring all the MS wires, I start to think how come the MS doesn't need to control the Fuelpump. so I start reading more, and I start to dig out many information.
In my wire harness, I left out Pin26,30,37,etc. so I do actually need Pin 37 to control fuel pump?

If I do, I am going to be pissed. all my wiring is set and fixed to my car, and it will be a PAIN to add it back.

Please advice!
