After a few weeks of slowly soldering and shrink wrapping all the wires. we have converted my friuends DX to MPFI.

This is not complete until we get the Si distributor so the crank angle sensor is hooked up.

Right now it runs like crap off the Si ECU for this reason but it does run


The question is: The yellow wire from the main harness that on the DX goes to the secondary injector is just laying there. Do you just leave it or do we connect it to somthing.

THX guys
