I need to match the remaining wires from the chassis harness to the Ls harness.
Check engine is a light that picks up 12v from the car and ground through the LS harness?. Speedo should be the signal to the speedometer, repacking the dash harness Speedo sender? 12v should be connected to crank/coil?

On the car harness I have 2 Speedo sensors that aren't used. Coil to tach that isn't used. And then coil crank to efi, right? Just one wire to go bang??
