    Right on man, thanks alot. I will be using an aftermarket fuel pump, not quite a stock engine haha. I will solder i just didnt want to redo all the connections thats why im using both ecus.
    -Would that single wire for the obdII allow for reflshing of the Ecu? Happen to know which wire?
    -will i need to get the old ecu flashed at all? or am i good to just rip the unused wires out of the old harness?
