sure I can do that, but I can tell you according to the manual that it will pulse 0v and 12v.

On the injectors, the way I see it, power comes from the relay, passes through the resistor, then to the injectors, which are ground out by the ecu, is that right?

And I've soldered the connections about an inch from the ecu plugs, so I didn't run any into the engine bay. I want to use the shortest wires possible to hopefully avoid the mass of electrical interference that passes through a car. I also twisted the wire pair, and they lead to the guino using cat5
