I'm about to do a similar setup.

The 4 connections at the bottom of the picture above need to have 5V pulse when the injectors are injecting. So it needs to be connected somewhere inside your ECU. (I can't exactly say where and how in your case) The signal outside the ECU is a grounding signal which will not work with this board.
If you want to just replace a resistor pack, you need the V2.0 board (for 4 injectors or the V2.1 board for 8 injectors). With the V2.0 board, you will connect 4 wires to the injectors and 4 wires to the ECU (like you would the resistor pack). In addition, you will need to connect 4 wires to ground for the injector grounds (which is no longer done at the ECU) and a 12V and ground wire to power the board.
The V2.0 fit in it's own box independent from the ECU. You can look at my post from Feb. 10 (on page 10) on this thread to have an idea of what it looks like and also at this: http://jbperf.com/p&h_board/v2_0.html. This is what the finished box looks like (without the connector):
If you're interested in getting a board, you can contact me by PM or by email (boards at jbperf.com).
