Going to my alternator there are two wires that go to the plug ther are red and blue. Which wire goes to the red from the external alternator voltage thing? I still have no idea which wire to connect the ms fuel pump wire to. What happens with the stock o2 sensor since it doesnt have any ms wires connected to it and the stock ecu is unplugged? How do i connect the speed sensor output to the speedometer? Whcih wire is the speedo wire and is there one close by the stock ecu location?
