Connect the jumper to where ever you are supposed to supply power for the new ignition. There must have been a wire or terminal the instructions for the new ignition said was the power connection. In other words, supply the new ignition with power connected directly to the battery, and thereby bypass the entire wiring harness of the Pantera. If you used the power wire from the OEM coil to power the new ignition, then remove that wire and use your 12 gage jumper in its place.
