I had the ground side of the meter held at a ground point so I really dont know what happened. Thats where the Guinness comes in.
To answer some of the questions........
I have a cheap little digital meter from radio shack - nothing fancy
The motor is not currently supercharged but thats the direction Im heading. Im trying to get the controls and extra diagnostic stuff in place first. I realise Im going to have to look at how much current each component needs. Sounds like a wire from the DME bus is the easy solution (Meir suggested black/brown at pin 56) but pulling too much current from the is scary.

the wire i suggested is basically the 15 feed to the ECU (AKA true ignition ).
the information was taken from the circuit diagram in the Bentley book (highly recommended if you have any intentions working on your car yourself)
this wire also feed power to other element in the car except the ECU (as mentioned in previous post).
adding a relay will drop the load on that wire, and will allow you to use a separate fuse for your setup.
select the correct fuse based on the current drew.
