If your familiar with your DMM, then you can probe for AC voltage. The trigger wire will show a couple of VAC and the power wire shouldn't. Conversely, you can bump the engine until you get lucky and find a grounding spot.

You should have an Ecoil with the TFI connector on it. So it's just the two wires. It should look kind of like this .jpg)

On page 32 dk grn/ylw is the trigger wire.
