good job lee. are you using the reley board. its aload easyer with wiring if thats used. and people, its really not hard to build one of these units. heres mine:

No I'm not using the relay board... because to be honest you only need one extra relay for the MS! And if you realy wanted to you could do a slight rewire of the ASD relay and use it to control the main MS power... I'm planning on trying that soon.
All you need is to make a harness for the MS, then you just have to splice into a few wires and voila, your good to go.

And yeah the Megasquirt isn't all that hard to make.
You can buy everything you need from www.glensgarage.com for $146 shipped. Or people like me can make one for a fee if you don't feel up to the challange. But it's really not that hard if you have soldering experience.
