I have all the harness, sensors, and ecu. I need to know what else is needed to do this convertion. I know the jugs are different from efi to carb, but it still should work. I think there is a sensor down by the track, what does that do? Also when you pull the pull cord what moves in there to tell the fuel pump to turn on? I'm sure I will have some more questions but I will get to those later. In case you guys are wondering I am turbocharging this sled. Any help would be much apperciated.
